Its a combination of things but regardless whether its 4 years, 2 years, 1 year, or 1 day, guys like St.Louis or Giroux have been, simply put, better. I'm glad Kunitz made, and I'm glad Sharp made it, because they'll have some cohesion and familiarity with their linemates (Crosby and Toews) but St.Louis really should be there to play with Stammer. Glad Staal didn't make it in either but Nash making it is a joke.
You need cohesion and familiarity to win such short tournaments (as well as solid goaltending) and I fail to see how Nash helps accomplish that. Especially considering he's really just a one-man highlight reel on the odd occasion. Where is the glue?
