If you think DK can take you to a NC, then yes, would be stupid. If the coaches think he is heads and tails the best option for the future of the program (not just this year), it would be stupid.
If you think we just went from 10 or more win team, to an 8 win team, would not be stupid. If the coaches think Wimbush has the talent or higher upside, not stupid. If you think the depth of the position over the next 3 years is important, not stupid.
Just my opinion, but Wimbush had the highest composite score of all of our QBs (98/45th National/3 DT vs DK 91/232nd/12Pro vs MZ 93/170th/4DT). I'm not saying stars are everything, but they aren't nonsense either.
It's not like DK got a ton of reps in the spring. He started by getting 2nd team reps for the fall. Those reps were also for plays designed for a MZ/BW type QB.
I'm not saying DK sucks, or can't lead this team, or is not the best option. I'm saying if the coaches believe the readiness is even close, it's better for the future of the program to make this year count if they have to blow the redshirt. Knowing BK, he will have packages for both if he wants a QB that can run.
