See the difference between Callahan and Nash is, Callahan gets mostly paid to do the little things, and provide scoring when he can, like in that Game 6 clutch goal or set up the GW goal against Detroit. Nash is vice versa, he is expected to pot goals or points almost every night.
I'll admit Cally has been way off in the middle of these playoffs but because he had his appendix removed. So his point production has been severely effected. But if he plays like he did the last 2 games, heading into the finals, Tampa's chances of winning the cup will go up a lot more.
A guy who scores 24 goals, and puts up 54 points in the regular season does not suck, it is just a desperate cry to convince yourself that you are glad you got rid of him, and the vultures are going to feed off his struggling which was highly due to his health. But he is off to the finals, and the Rangers are not. Justice has been served.
