Not only does he know the offense, he's a known quantity to the coaches. I have every confidence that the game plan will set him up to do what he does best, and that he will execute that, whatever it is.
He's not Tua, and won't have that kind of accuracy. But there's no shame in that....just about nobody other than Tua does. I don't know what sort of runner Mac is, so I'm not sure if we'll run the same offense we do with Tua, or if we'll revert to more classic running game and play-action pass, as under Jake Coker and AJ McCarron.
It's a small sample size, but he has started slow in A-Day games and the few times he's been pressed into service due to injuries to the starter(s). I'm hoping the week of physical preparation, and more importantly, mental preparation, will help him mitigate the butterflies.
In that same small sample size, however, he also has a history of settling in and doing fine once the butterflies settle. I expect neither passing records nor an implosion.
We need to build his confidence, and I do worry a bit about the weather. Current forecast is not good.....70% chance of rain, possibly heavy, and lightning also possible. Maybe it gets a little better in the next couple of days, but that would be a reversal of the current deteriorating trend.
Last thought -- I would expect Arkansas to stack the box to force the green QB to pass. Which might be a mistake. If stacking the box puts our WRs 1-on-1 against Arksansas' DBs, I have to like the WRs to win the majority of those matchups. Which could lead to successful downfield passes where accuracy isn't quite as crucial as it is when you're throwing middle slants in lots of traffic.
