Getting Traded

Don't know. But the mere fact that a head coach is also holding religious services for his players is alarming and should be cause for investigation. Doubt playing time is affected; you're not going to sit a starter just because he's a "heathen' in the eyes of the coach. But it may very well have affected Jackson's relationships with his assistants. And it could be a factor as decisions are made over bench players going into each season (if Mark has a voice). IMO, there's a HUGE difference between being religious and even attending a pre-game prayer with any players who want to participate vs. being the one holding/conducting actual services as the minister and transporting players to those services.
This could be the major reason they let Jackson go. All the other reasons they gave are just excuses for something they're not revealing.
