I think Richt has definitely handcuffed an already limited offense with some questionable play calling for sure. Everyone knew Rosier wasn't a good QB last year but Richt did him a lot of favors. They would run a stick/bubble combo at least 10 times a game and it would give Rosier an easy pass against almost every type of coverage. That's often why you'd see them run like 4 or 5 bubbles in a row against teams playing off in coverage. Yeah, they're not game changing plays but an easy pass for a limited QB that gets you 5 or 6 yards at a time is a win/win.
Personally, I think Richt would get a little too pass happy at times last season and when you throw incomplete on first down, it sets you up for a lot of third and long type situations. I believe he's tried to over-correct that issue by forcing the run too often and then relying on some type of vertical throw if the runs get stuffed. It's funny because their third down percentage has actually gone way up this season despite the scoring (against p5 teams) going way down. It's almost like Richt was so desperate to solve the third down issues, that he completely ignored the other facets of the offense. It's a delicate balance, you don't want to rely too much on an early down pass with a poor QB but you don't want to be so desperate to set up a third and short that you just blindly run your guy into a pile on first and second down.
