I've never been so sure about something as I am this:
It will continue to get worse with Rex. He has shown me absolutely nothing which would lead me to believe otherwise. The discipline issues did not get any better. The defense got worse as the season went on. The players quit on him.
If he stays, players will want out, fans will be fed up, and he'll continue to dismantle this team to where it will take years to build it back up.
This guy needs to go, now. The team is not beyond being saved for next season. But if he stays, we can tack at least a few more years on to our playoff drought. I just don't see this situation getting any better with Rex.
