I do agree that Stanley's misses are magnified because he overthrows his open receiver. However, Stanley does obviously have a really good understanding of where to miss because he hasnt thrown one ball so far that had even a remote chance of getting picked. And he his hit a lot of throws, he has a 64% completion percentage and that includes some throwaways and a few drops.
I dont think there is anything to nitpick here, yet. Lets see how he does against UM, Wisky, NW, PSU, etc. As that will define his Iowa career.
