Well we did already see Thornton and Toews go at it recently.
The only Captains that could give Thornton a run for his money are Weber and Chara.
I would say Iginla, Backes, Staal, Ladd and Phanuef would be good bouts but I'd put my money on Jumbo everyday. We already know what happened with Getzlaf
Now if Lindros came back that's a different story.
