I guess I would question whether this was actually the "plan". Yeah, I'm sure Jacoby came in as the defacto starter, as any veteran should over a rookie. But if Maye had shown immediate command, I think there was definitely a path to him winning the job. I think there was a competition, it's just not always easy for a 21 year old rookie to beat out a 9 year veteran right away. And what we see in preseason isn't the whole story. I've seen breakdowns of Maye's film that show he's got some things to clean up first.
And (thought they'd never admit this publicly), I think they want to get their house in order a bit first before Maye steps in. Mayo first time head coach, AVP and Covington first time (basically) playcallers, and an OL that's still in flux. It's not that they don't care if Jacoby fails or gets hurt, but getting him mentally prepared to play is one less thing they have to worry about while finding their footing. The competition is about more than who completes the most passes. There's a LOT going on behind the scenes that we just don't have access to.
