I'm not saying that some criticism isn't fair, but I have no interest in changing coaches. Good coaches are harder to find than talented players, IMO.
Coughlin and KG got us to 2 SB's, and Fewell helped us get to one. And the assistant coaches are good to including Pope, and the line coaches as well. The ST coach has done a good job over the past two years, but I think that Weatherford was the biggest factor there.
If high-priced player seem to lack the desire to show up, then that's on those players. They can take a hike.
