The turnovers are largely a microcosm of coaching and confidence. Something obviously isn't clicking somewhere. I don't know exactly how much fault to put on Satt but he bears a majority of it. As the OC and QB coach, it is a tremendously awful look when all three of your QB's can't execute the offense you installed and make awful decisions with the football.
I don't always think some of the issues are explicitly the QB's fault (it did look like the WR held up on the end zone INT) but still it all goes back to what's the play call, what are the most important things to execute on the call, and how do you ensure you protect the football. Even with all the injuries, It's baffling that they're in week 10 and some of the simplest elements of what needs to be executed just... aren't there.
