I say just run the offense. Tailor it a bit to suit what he does best, but just run it. He will now have all week with the starters, and will hopefully get in sync with the WRs.
OL needs to play with a fire they've not shown a lot, but I fully believe they are capable of. They were already starting to come around over the last couple of weeks.
The defense is what it is. We can outscore Arkansas. We can outscore Mississippi State. Beyond that, just get Tua healthy, but let Mac run the thing as normal as possible just in case, so he is as ready as he can be.
