If I'm JR I'm firing Rivera and letting Chud have a lame duck season. Rivera isn't getting it done and Chud actually showed he could be a decent coach...albeit last year.
That is one of the worst things we could do unless we want to intentionally tank the season. The biggest thing holding this team back is our offensive strategy. If you promote him he will still have full control of the offense and if Rivera has any positive impact our defense then our d would be even worse.
I would love to fire chud tomorrow and let Shula or whoever the most ready guy is take over the offensive scheme and play calling.
