I think the biggest issue right now is (based only on my opinion and a modicum of research of course) what Richt is running and what Richt might WANT to run are at odds. There's no doubt that he's getting the absolute most out of Rosier - warts and all - but he's doing it by severely limiting the offense to play to Malik's strengths. Malik is a one-read QB right now, and he's got the arm to put it where it needs to be, hence all those passes into tight spots. He also often processes information a tick slow (passes thrown late, behind, or not at all.) It's also why it appears our WRs get little separation on timing routes - by the time Rosier gets there, the DB has closed the gap. He's not a "throw guys open" kind of QB.
Based on his history at UGA, I suspect what Richt wants to run is some passing triangle/shallow cross concepts sprinkled with RPO and a power run game. What he's been running and is GOING to run with Rosier is a read-option, 4-vert, screen-based passing attack. He still wants to run power concepts (pulling guards, etc.), but man our OL just isn't there yet - hence the struggles in the run game lately.
Now we've been winning with Rosier and that's a testament to Rosier's sheer will to lead and get better and the coaches' ability to tailor our O to his strengths, but we are what we are right now on offense - limited.
BTW, the UNC game is vintage Richt - one of the big complaints about him at UGA was playing down to the level of competition, even during wins. Every coach has this issue to some degree, just be glad we've been coming out on the winning side so far.
On the first thread you referred to, if you'll look at what you said about the receivers/throwing game - I haven't seen much of that out of Richt. Crossings, X's, or drifting tight ends.
Do you think that currently, Rosier has too much time to think? I mean, when we go uptempo - it's like our receivers bust their move, Rosier (even if he's a one-read dude) can actually get it to them, as it's so quick - the receiver is open -and he isn't burdened with thinking or having to worry much about progressions?
If so, uptempo may be something Richt may want to consider.
