Our small forwards are Pageau 5'9, Conacher 5'8, Hoffman 5'11, Alfredsson 5'11 everybody else is 6'0 and above and the players mentioned play bigger than they are.
The height isn't the concern, its the body mass and strength that is of concern.
Conacher (179), Condra (189), Turris (193), Pageau (163), and potentially Hoffman (176).
I have seen most of these guys in street clothes and I would be willing to bet several don't come close to these weights, starting with Turris.
Adding Briere 179 to this group really doesn't make sense unless the plan is to be a copy of the Canadiens.
I am not against smaller talented players, however having the equivalent of 2 lines filled with players under 190 lbs is not the key to success in today's NHL. This is especially so when many of then will be employed in 3rd or 4th line roles.
