Other than the long ball to Ostrenga, I don’t recall a pass going downfield beyond 10 yards, max. Maybe there were routes run past 10 yards, and they were covered or Sullivan didn’t see them, but on tv it’s hard to see that far down the field until the ball is thrown.
He seems to check to running quickly. Again, it’s hard to tell on tv why he’s doing that - no one open or he’s not being patient enough. If it’s the former then he’s a good option because Iowa will need a QB who can run. If it’s the latter then he’ll need to work on that a lot over the next 8 months.
It’s hard to judge without more information.
