It's becoming increasingly difficult to imagine Trestman will have say in critical decisions moving forward. The defense is an abomination again this season and the offense has been reduced to a spectacle. While cleaning out the coaching staff with Trestman having two years remaining on his contract and with coordinators believed to be signed for one more season isn't the kind of business decision the McCaskeys have been known to make, it might be inevitable with three games remaining as the Bears prepare for Monday's game against the Saints at Soldier Field.
