I'll jump in on this, QE was young this year and had a lot to learn. While he is a R-FR, this was his first live action in 2 years. There was a lot to learn from setting protection, reading the defense and adjusting to it, having to read through his progressions and learning that he can't just rely on arm talent
I believe there will be a switch that happens (maybe it did) where the game will slow down for him. Bottom line is Sark knows QBs more so than any of us and he sees it in Quinn and will make sure all of those adjustments are made in the off-season. Remember, there was 0 film for Quinn to learn from.
