Actually it is a coaching issue. Throwing picks can be bad decisions and it could very well be offensive formation, route running, and the inconsistent flow and horrible run game can put QBs in a position where they feel they need to sling it to convert downs.
False starts are a discipline and an offensive rhythm issue as well.
Don't get me started on fumbles. We have consistently been a horrible team when it comes to fumbling, and it's not just one or two people, it's everyone, from last year to this year. I'm not sure what type of fumbling drills we do or don't, but it IS a problem
This isn't all on the coaches, but they take equal accountability for sure.
