Thr complexities of a college offense and the responsibilities of the QB are immense. I know some Greek, it isn't even a close comparison. All of the areas you list are static, only based in what Nebraska does. There are some teams that would love to get into the head of a true freshman QB.If Raiola isn’t the Day 1 Starter, that falls more on the Coaching Staff. The playbook doesn’t need to be like learning Greek.
I think, physically, he has the tools. It’s also a team sport. It ain’t tennis.
With the D we have and the early portion of the schedule should make it where there shouldn’t be a ton of pressure on him to win the games. Lord knows the offense didn’t win any last year. We won’t be in any shootouts early on.
I’m sure there will be a special emphasis by the Oline to protect nephew.
With Dante, Emmett, and the pieces we have at the WR/TE position, emphasis should also be on those positions to pick up their game and not make it where DR has to put everything on his shoulders.
If someone held a gun to my head and had to answer the OPs question I would say DR is the starter based on the names we know right now. That said, I feel equally confident he will struggle. How much and how long remain to be seen.
