The pressure stats will say it all. Coaches have to figure out a way to put them into game situations to determine the starter.
If we're laughing at Franks for how crappy he is under pressure, go back and watch Perry under pressure and look at his stats. He's worse. The Perry of 2019 would lost the starting spot 10 out of 10 times to Martell.
The good news for Perry is it's 2020 and he starts with a clean slate. He was a project coming in, and had zero development from John Richt. So this is his first real QB coach in his career. He was also a little immature, and looks to be getting mentally stronger. So, yeah, I could see a major leap forward with him. But just throwing dimes in shorts with no threat of being hit by Garvin and company doesn't really impress me. Brad Kaaya was a first-rounder in that controlled environment.
So until Perry proves it, I'm rolling with what I saw on film in Tate's Spring Game, Ohio State games and high school games. Limited to be sure. But consistently shows he can make plays and his best quality is when he is under pressure.
