A lot of how Rockford looks will depend on who Chicago keeps and who they send down. Probably room for 3-5 Hogs' forwards on the Hawks this year, that will pretty seriously deplete their strength up front.
I could debate the intangibles besides +/- . Face off percentage (I believe he was Top 3), leadership (which I hear the unbiased experts on NHL.XM, TSN, NHL Network say Johnny is the best leader in the game), and, as you pointed out, the fact that he is 40-1 in "best on best" play for his career. Captain of 3 Stanley Cup winners, Conn Smythe winner in 2010, 4 time nominee and winner of the Selke award for best 2-way player, etc, etc, etcv. I don't think your GM.Coach argument holds water at all.
However, again I say, we agree to disagree.
