And who is this magical player going to be?
If your only criteria is "somebody that cares about winning." which means jack shit because you don't get to the NHL, NBA, MLB, NFL, whatever it is if you don't care about winning.
But if that's your only standard let's trade them both for Wayne Simmonds clones, because I assure you NOBODY cares about winningmore than he does, I truly believe that, I believe Wayne Simmonds would sacrifice just about ANYTHING to win.
Now obviously that's ridiculous but that's my point you can care about winning all you want, you can be willing to die if it means you win, Wayne Simmonds might be that guy.
But if you aren't as good, you aren't as good and you aren't winning regardless of the sacrifice you are willing to make.
