It was Richards first year. He had injuries and holdouts to deal with and still led the top scoring defense. But hes gotta go? Gtfo with that. Does he have a lot to learn? Certainly. Is there room to improve? Definitely. How about appreciating the good and moving forward with it instead of focusing on the negatives and calling for him to go? What if the next guy leads the league in scoring but doesnt make it to the SB? Gonna fire him too?
Coaches are just like players. They learn year to year, and can develop and improve. You dont just go firing any first year coordinator because things didnt go perfectly.
Well you do, if you're a shvtty franchise.
