I think some of our Hawkeye friends would rather downgrade him now and be right until proven wrong than get their hopes up for something and being disappointed...I don't get that, but it is what it is, I guess.
Look at Mark Vlasic as an example of a player who worked hard and got his chance with the Chiefs. He was going to be there starter after finishing #1 the year before and then a bad knee injury made him trent green before trent green was around.
Vlasic as everyone knows only started one year for the hawks and filled in well his junior year. He had a big arm but little experience. A few years in the pros and the light bulb went on. A bad injury really messed up his chances.
Stanzi might take the same route. Get some good QB coaching, work on his touch. He can make the hash throws and has generally good accuracy so maybe he gets a chance some day.
