I agree with PD here. You don't throw Rising out there for the first time against Georgia. If anything, you use Rising if Buechele stinks the place up in relief.
This spring, however, I start giving both Rising and Thompson more snaps. I think they'd both overtake Buechele by start of next season.
Years ago I was some sort of star in the making. I was brought up to varsity as a sophomore QB. I rode pine behind the starter until about game 5 when we took on state champion Paris. Starter went down in the 1st qtr. So I was pummeled for three quarters on a very hard field and ate some sod.
I still have nightmares about that night. lol
