^^This^^. I don't get the bagging on Zeb. He didn't play bad for us. I think CMC just wanted to give Brock some reps and he just lit it up. Zeb knew what was ahead of him here and decided to go elsewhere.
Now he is the #2 QB on a team who's last two starters are in the NFL. Who knows what could happen from here.
I liked Zeb. I recall making arguments that he was better suited than Kempt to utilize Butler's strengths.
I did question the timing of when he left though. It seems like he got a pass since it was clear that he wasn't going to be the starter if he stayed at Iowa State, but I always thought leaving as early as he did was selfish. He left us pretty thin at QB and the team had plenty to play for.
