Wrapping up the undrafted free agents series with a Boston Bruins focus, going with four players who were in the AHL last year with the Providence Bruins. We could see one or two of them get some NHL games in with Boston this season depending on how things go.

Before we get to the four prospects, though- a little housekeeping first:

As reported in the Boston Globe, Gretzky to the Oilers as assistant GM is done, with Don Sweeney wishing his former chief scout well, lamenting the timing of the hire as an issue. Not one to stand in the way of letting their employee advance in a key managerial position even with a rival club (rival for obvious reasons I don’t need to go into), the B’s did the right thing by letting Gretzky go. This is one of those “if you love someone set them free” kind of things; the team could have played hardball, but that usually comes back to bite you. At this stage, the B’s don’t get anything for releasing Gretzky except maybe some goodwill and the hopes that they can build bridges with their former GM now in Edmonton rather than burn them. I saw someone (I don’t remember where it was) mention the other day that a Dougie Hamilton to the Oilers for Taylor Hall might have been something worth doing if relations between the teams hadn’t been so strained. I don’t know if that was even realistic to consider a year ago, and the world will never know, but cordial relations across the league are better than adversarial ones.

Now, former director of amateur scouting Scott Bradley, who held the post with Boston for more than 10 years before Wayne Smith was named to the position in 2008, will wear two hats as assistant GM and chief scout until Sweeney can find a replacement. Bradley is a good man who has spent nearly three decades in the Bruins organization. His watershed draft as scouting director was 2006 when the team landed Phil Kessel, Milan Lucic and Brad Marchand with three of their first four picks. Bradley was the guy most responsible for Lucic and a decade later, it was a hell of a find. He’s a man of integrity and a cancer survivor whose decency and dedication to the profession has earned him a great deal of respect around the league.

The Bruins are in good hands until a longer-term solution is found.

Now, onto the main topic at hand…

This is the last in a series of articles on undrafted free agents who have made an impact with the B’s: Torey Krug, Frank Vatrano, Noel Acciari, Tim Schaller and Kevan Miller. It’s pretty rare to have four UDFAs on one roster, and the skeptics would probably tell you that it might begin to answer why the B’s have DNQ’d for the NHL playoffs in each of the past two years.

Having said that, Krug has become an integral member of the Boston defense, while Vatrano shows a great deal of promise as someone who could net 25-30 goals or more down the road with a natural scoring knack that can’t be taught. Miller is a trusted if at times miscast defensive defenseman, while Schaller and Acciari are Providence College products who look like above average bottom-six players at the NHL level if they can keep progressing. If nothing else, they’re key cogs at the AHL level.

Now, we look at four players who have yet to reach the NHL, but show enough promise to get there. It won’t be easy for any of them, as with the exception of Czarnik, none display any real higher-end potential. However, as we have learned over the years- sometimes all it takes is an opportunity. This group is likely ticketed for Providence, but stranger things have happened and injury woes or exceptional play could see one or more of these guys get a shot at the big time.

Austin Czarnik, C- Often overshadowed by Vatrano’s scoring eruption last season, Czarnik had an outstanding rookie pro season in the AHL, posting 61 points in 68 games and impressing everyone from the get-go with his speed, smarts and hustle.

The former captain of the Miami University RedHawks was snubbed in the NHL draft because of his lack of size, but he’s always had pro-caliber wheels and brings creativity and moxie to the mix as well. He was recalled to Boston late in the season on an emergency basis but didn’t get into the lineup. While not an ideal fit on the third or fourth lines given the B’s current personnel, if anything changes, the team won’t hesitate to put him in there.

One play in the preseason last year really stood out as typical of what the little Michigan buzzsaw has always been about: on what looked to be a routine dump-in to the offensive end, Czarnik could have made a line change, but he recognized his opponents were making a change and a sloppy one at that. In an instant, he turned on the jets, and blew past a defender who was on the way to the bench but couldn’t adjust his trajectory in time. Czarnik got to the puck first and then made an on-target pass for a Boston goal. Those are the kinds of plays that earn trust and respect from the coaches because of the skill and intelligence behind them. At the NHL level, nanoseconds can mean the difference between making a play and coming up short, so Czarnik seems to understand already what is at stake.

Now, exhibition play isn’t the regular season, but it spoke volumes that one so young and inexperienced at the pro level came in and clicked right away, performing at a near point-per-game pace in the minors. Watch for Czarnik to make his NHL debut this season. He’s probably not going to begin the year in Boston, but he’s a solid bet to get some games in because he’s got scoring chops but is also working on improving his all-around play and is not a defensive liability.

Here’s his first career pro hat trick from December:

Chris Casto, D- The B’s signed Casto out of the University of Minnesota-Duluth in 2013 and at one time, he was shaping up to be a top Minnesota high school draft prospect. With good size and skating, Casto won’t win on many style points, but he can really fire the puck and he put up the best offensive totals of his three-year professional career in 2016.

Casto is a smart and solid positional D. He plays a similar style to that of Tommy Cross, but without the second-round pedigree (and as-of-yet unfulfilled expectations) hanging over him. Casto keeps things simple: he doesn’t show off much in the way of flash, but is steady and moves the puck to the right areas. Like anyone who logs a lot of minutes, there are times when he’ll make a mistake that leads to a goal, but at the AHL level at least, he’s developed into a top-four presence who first-year Providence head coach Kevin Dean will likely lean on heavily in the new campaign.

Here’s a slow-mo video of a Casto goal from last season:

Colby Cave, C- It was a bit of a surprise that the B’s successfully signed Cave after they grabbed Czarnik and Vatrano in the spring of 2015 because Cave was viewed as one of the top undrafted free agents coming out of the WHL a year ago.

The former captain of the Swift Current Broncos saw time in 2014-15 with Boston first-rounder Jake DeBrusk, and had a solid if unspectacular first pro season in Providence last year.

Cave is a fine skater who is effective on the fore check and at forcing turnovers and plays a smart, capable two-way game. What you see is what you get with him- he’s going to take pucks to the net and make an honest 200-foot effort to compensate from a pretty average skill set. He plays the game bigger than his size, playing a rugged but clean style and his leadership no doubt appealed to Boston in their aggressive pursuit of him.

Watch for Cave to put up 20 or more goals in the AHL this year if he can stay healthy, and he could line up behind Czarnik in Providence’s top-two forward lines with the departure of Alexander Khokhlachev to the KHL. Players like Cave aren’t all that sexy or exciting, but they’ll get a shot sometimes ahead of the flashy but one-dimensional types who can only play on half of the ice surface.

Cave’s biggest problem is that he’s got Acciari and Schaller to contend with, and I don’t see him beating either guy out for a spot in Boston, so he’ll probably have to bide his time and try to elevate his play on the farm to make a case.

Cave’s first AHL goal is at about 1:02 of this highlight vid:

Justin Hickman, RW- Another WHL captain- the Bruins outbid several other NHL clubs for the Seattle Thunderbirds overager in January 2015 when he suffered a shoulder injury and had to shut it down for surgery.

He gets a pass for a mediocre rookie pro season because of the physical, rugged style of play Hickman brings and he looked a bit tentative at times as he adjusted to the pro pace after missing about 10 months of playing action by the time he started skating in the AHL.

He’s got good size and toughness- Hickman isn’t a heavyweight who can go toe-to-toe with the biggest, baddest fighters (admittedly- there aren’t many of those left), but he will actively drop the gloves to defend himself and teammates and loves to initiate contact and do the heavy lifting along the walls and in front of the net. Here you go:

Hickman doesn’t have an abundance of skill and best case for him would be to eventually land on an NHL third line somewhere as a middle-of-the-road option; he’s more likely a solid fourth-liner similar to Nate Thompson (who was coincidentally a Seattle product as well).

Stats don’t tell the whole story- Hickman was eased in and didn’t have much in the way of opportunity, but the B’s are quietly high on him and he’ll get a chance to elevate his stock as a sophomore. He’s not ready to make an NHL roster push, but a strong second pro season would go a long way for his confidence and give the team some options.
