well...i think its more a matter of wanting to build a team with his own guys....cooper wasnt his and, despite his talent, has underperformed and is a reminder of the last failed coach.
I dont blame him...he wants to build his own team and now has 5 1st round picks in the next two years.....and will probably have more on the way. If i were a raiders fan, i would be pretty excited to get through this season and start the offseason....in 2-3 years they are going to have a shot at a decent run if he drafts well.
