I'm not gonna sit here and act like an OC whose unit was pretty much bottom feeder most of the last two months of the season is some type of legend, but if you think firing the OC is going to be an elixir for the QB's failings you're wrong. Its hard to call plays for a QB who isn't reading the field at a starter level week in and week out. The QB throws after the receivers make their breaks, not before. The QB throws passes high over the middle when he throws them at all, which is rare because he's not comfortable throwing the ball when guys aren't Alabama open. And guys won't be Alabama open when you've got one NFL caliber receiver on your depth chart, and that's when he's even able to play on his gimpy hamstring, so you can't go downfield because nobody has the speed to do that, so teams sit underneath and your QB can't throw guys open because he doesn't have the comfort, confidence, and game feel yet.
Sure, fire the OC...but it won't fix the problems with any OC would have been hugely burdened with. I'm not even sure what role Chan had in starting Tua, whether it was his call, if he had a say, and if he had to make it work. Tua looked completely overwhelmed in his first start and outside of one game it really wasn't even that much better. The rookie QB, who had no preseason and a crazy practice environment due to covid, wasn't ready.
