On the Bengals signing Palmer

If the Bengals are changing for the better, why do Takeo Spikes and Corey Dillon what nothing to do with the place? I could be wrong, but if you compare the players coming and going the Bengals are not securely in the positive this offseason. Lewis may indeed change the fate of the franchise but he'll do it by being a better coach and keeping his players playing hard, neither of which happen in April.
