If you watch all their video Labas and May jump off the screen as far more advanced and athletic than either Spencer or Alex.
Spencer looked like an incredible passer. When you watch those throws now, and I did over Thanksgiving weekend, Spencer's throwing to a lot of wide-open receivers downfield. It seems like his team was kind of a talented crew and Spencer never faced pressure. Personally, I think Spencer's mentally shot, no confidence that he's making the right read, hence the hesitation and wild throws
Alex's film was not as impressive. You could tell he played in a much faster offense and seemed quicker than the average Iowa QB. He just didn't seem to have much running instinct. Good thrower but not a great arm strength or form.
Labas and May throw better than Alex, much stronger arms and have a more natural running instinct. A nose for the hole and better field vision.
Do not be stunned if Alex and Spencer transfer.
