Right now...Ribiero is not what's needed on the second line and probably never will be. Whats worse, is that as long as he is in Montreal, this is where he will be. He does'nt quite fit anywhere else does he. Definitly not a first line centre, a pretty weak Third or Fourth line centre and to even consider him as a winger on Any line would be absolutely outrageous. So the second line is stuck with Ribiero for now.
I would rather see a fast skating two-way centre in ribiero's place, one that can make players around him better in all situations and also brings some Veteren leadership. With all the young guns on the team now, its good to have players that will set the tone for the next 5 - 10 years, i dont see Ribiero as being one of these players who lead by example.
Ribiero is Too One Dimensional. Most of the time i find he waits for chances and needs room to perform.
Not to take anything away from the kidd, but he's obviously not whats needed.
