Those guys always get more though. Not saying we should do it, but someone probably might. he is only 21, so it's early to call him a complete bust, there is still a lot of upside. I would however let some other team take a chance. While I'm no Bennett expert he looks a lot like Ryan Spooner from what I have seen, but he is a lot more aggressive. Change of scenery could be the magic ticket.
He's also a lot like Spooner in the sense that he was drafted as a Center, but at the NHL level, he's primarily been used as a winger. Took just 200 face-offs last year in Calgary, 5th on the team (I didn't include Nick Shore as he was acquired at the deadline), and the 4th most, Stajan, took over double the amount of face-offs Bennett did, indicating he's most played wing.
One thing the Bruins don't really need is another left shot winger. You could almost say they have too many now signed for next year (Marchand, Debrusk, Heinen, Donato, Bjork, Cehlarik) with still a full off-season to play out.
