He's a good offensive player but confidence seems to be a big factor on his game. Examples like the beginning of the season where he should have made the team out of camp because he was the best player out of the group he was competing with, but was sent down and his game struggled. Also, this most recent stint up where he started off really well, got benched a few times, and his game plummeted.
Cehlarik may be one of those guys that needs to be with top roster talent to produce, and even then it's not consistent enough. It would have been nice to see him on a 3rd line with Coyle and one of Johansson/Heinen. He struggled with Backes, like every player did. That would have been a way to really see if he can produce with that "next tier" talent.
I do hope that Boston trades his rights and doesn't let him walk by not qualifying him if they don't plan to bring him back. However, seeing they let Connolly and Czarnik in that fashion, Cehlarik may follow that route.
