The top end of the D in 2001 is far more solid (Aucoin, Jonsson, Hamrlik) vs (Boychuk, Hamonic) however the lower tear is weaker than 2014 (Haller, Kiprusoff, Martinek, Cairns) vs (Reinhart, Strait, Leddy, Hickey) especially when you factor in DeHaan and Vis missing from this year's lineup. Forwards are pretty close, a lot more youth in this year's lineup....
