Sometimes it's all about how a QB is being used. Square pegs may not work in round holes. Our very own Tim Couch was being used as an option QB under Bill Curry. If I remember correctly Tim said it's either him or the coach and the coach was fired. Once Tim was in the scheme that matched his skill set, he exploded. You just never know.Lots of kids in high school come in with tons of accolaids and don't produce. Iowa has had two 5* OL recruited in the past 15 years and both proved total busts. It happens.
What I'm saying in my original post, I guess I didn't say it unless you read between the lines, you're getting a QB who has played enough snaps in his first two years of college to count on 2 hands. He was unable to beat out two pretty below average Power 5 QBs who ran ahead of him on the depth chart, and when he announced he was leaving Iowa may have actually been #4 on the QB depth chart.
I do hope though Duece can see the field at UK at some point.
I wouldn't start making plans for a serious run to the CFP as your QB.
Watching his HUDL videos I see a good but not great arm. I also see good touch. He seemed to run pretty well as well. It's possible the game is just to fast for him at this level but the basic tools are there. Should prove interesting to see what happens.
