Against P5 competition, Carson Beck has a higher yards/att than Miller Moss. And Beck is not really throwing the ball downfield (outside FSU). The reason he has so many pass attempts is because they dink and dunk down the field. Their strategy on offense is going to be getting the ball out of his hands fast because A) that's what they normally do and B) it'll attempt to limit the DL effectiveness. When Moss gets in trouble is when he needs more time. Every game I've watched it seems he has no time to throw on deep routes.
What seems to be effective against them is to bring pressure. You don't need to send multiple guys but continue to send pressure from different areas. It has messed up his timing. Then drop those guys back every now and then into the passing lanes. I think you can get Moss to throw some INTs. They want to get rid of the ball so fast that I don't think he's doing a lot of progressions. It's a one read offense mostly.
