Some have hit the nail on the head. I have trouble believing that every receiver on the football team can't catch. On every throw there are two people involved; the receiver and the passer. When you use the control method of scientific experiments, the passer is the same. The receivers are different, but the result seems to be the same. In a scientific experiment that would mean you need to change the control, change the passer and see what the result is before you can analyze fault.
Lee is horribly inaccurate. History shows that the "dropsies" tend to either end right away or get continually worse. Now, when they do end quickly that is usually on the receivers. They weren't concentrating, or an issue with spin. These same WR caught the ball pretty well with Ganz. I don't remember many drops from anyone still here but Gilleyan with Ganz at QB.
Here is your main problem, leadership. There is no leader on that offense. None whatsoever. Say what you want about the OL yelling at Tray, but that was at least some passion out of that side of the ball. It wasn't directed correctly, but it was passion. Watson isn't fiery, Lee isn't fiery, Helu isn't, the WR sure as hell aren't. Where are these guys with a burning desire to win at?
Look at the defensive coaches. They instill a fire in their guys, those guys would run through a wall for them. Only Cotton has that right now from his guys. Say what you want about his line, those guys played with fire on Saturday.
We need a passionate leader on offense. Players from every team say that is easiest from the QB position.
I think A LOT would be fixed by a QB change. I just don't know if we have that QB on our roster, but I would sure as hell like to find out if that guy is there.
That is all.
