Neither Purdy nor Kempt are NFL quarterbacks. Between the two, I think Kempt had the better overall skillset for a college QB. Smarter, even tempered, able to read the game much better.Purdy is the winningest QB in ISU history. I can make an argument on both sides that he contributed to those wins while also holding them back.
I tend to error on the side of him holding back the team. Our best roster in school history won 7 games. QB is the #1 reason for wins and losses.. Dead arm Kempt with less of a roster.
1) Bad turnovers
2) Lack of ability to stretch the field
3) Size
4) He seems to get some tunnel vision
Overall he was a good player and a great person. ISU is a better place today than when Brock came to campus.
It's all conjecture and amusement of course, but I think with a healthy Kempt instead of Purdy the 2021 team wins 11-12 games (including a major bowl).
