If it came down to 1 roster spot between Carcillo or Doresett.. I'd re-sign Carcillo and trade Doresett.
Carcillo gets his job better and has just enough crazy in him to keep guys at bay. Played very well, and has been reliable in D-Zone starts on both LW & RW.
Also gets under the opposition, making them lose focus, start scrums, and has stood up for teammates.
The prime example was the Neil hit on Moore. Didn't drop the gloves, but didn't hesitate other. Dom Moore stood up for himself on the play too. Moore wouldn't have gone after Neil if Carcillo wasn't there.
I don't think Dorsett has that effect at all. Even though Carcillo is a 4th liner, he's provided a spark, and just solidified the 4th line playing off of Boyle and Moore. Team is above .500 after the trade, same with GF-GA.
With Carcillo, Boyle and Moore all being UFA's, I'd be hesitant to move Dorsett
Since this is a cap world, you'd have to see what those Free Agents would be asking for...
Dorsett is contracted at $2M next season (which happens to be his contract year)
Boyle is due a raise, probably around $2M
Moore is due a small raise, most likely to $1.3-1.45
Carcillo may only be due his his maximum salary as an NHL player of $1.045M...
So, 4 4th liners for 3 spots...
You keep Moore and Carcillo. Then it becomes between Dorsett and Boyle... That breaks down to two things:
Dorsett is the more offensive player of the two, who can actually fight, skate decently, kill penalties, etc
Boyle is the more defensive player, who excels at faceoffs, defensive zone play, and heart and soul...
It's a toss up. The only thing is that ONE of these guys can (and probably should) be traded for a draft pick, so who knows..
