It's the head coach's job to evaluate talent - including his staff.I get it and your points are valid. I had all the same concerns with our offense. I tried to incorporate the QB issues, along with what was many times poor execution (blocking, dropped passes, etc.). Overall, with the apparent improvement (minus the tater game), it felt like maintaining continuity with much better execution would be possible this year.
We now have enough sample size to know we need a different approach IMO.
