I wouldn't say that Dermott has out-performed his draft slot. He was picked 34th overall, so he was just shy of being a first round pick. And though I like him, thus far he's yet to prove that he's more than a very good bottom-pairing defenseman. With Rielly out, he's got his big opportunity now.
Ditto for Timashov. I mean, I guess making it to the NHL at all as a 5th round pick is surpassing expectations, but it's obvious he's little more than a depth player/borderline 4th line forward.
Johnsson & Engvall on the other hand? A couple more home-runs courtesy of Thommie Bergman.
