The main difference with the Hawks and the Rangers is the coaching
Besides what I said before, look at all the cup winners in the past 6-7 years maybe longer.
They all had something in common.
Top 5 center. Top 5 D-man. And at least
good goaltending.
Kings - Kopitar, Doughty, Gaborik, Carter, Quick. Hawks- Toews, Keith, Kane, Crawford, Niemi. Penguins- Crosby, Malkin, Kessel, Letang, Murray. And Etc.
Rangers in all their contending years have had great goaltending, but no other game changing players.
