I think the vet/role players are showing their importance. Although not "flashy" or the upside of guys like Morin, Leddy, etc .... what guys like Pisani and Johnson (even Cullimore and Boyton on the blueline) bring is a vet presence. They may not lite it up, but Johnson was good in the faceoffs and in his own zone. Pisani is a guy thats been in some big spots in his career and won't panic and make smart plays with the puck, take good routes when backchecking (this goes unnoticed alot)...and just do the little things right. Those guys dont have to learn the game - just learn their roles and the system.
I think Sharp is good at center - when he has Hossa at his wing (one of the best defensive forwards in the league). Without him, his own zone play suffers. It'll be interesting to see what Q does when he comes back.
