Because we don't have to chalk up 2009?
Because we could just put Gailey in charge for a year instead of Herm?
Because it's probably better to get a young coach instead of a retread?
Because there's no way Parcells, Schottenheimer, or Dungy coach again?
Because we want to signal that this franchise is changing direction?
Because we want a competent coach that won't destroy our FA and rookie classes?
I dunno, it's a mystery why Herm should be fired.
