Can we look at the numbers (on field production)?
This year--18 receptions for 304 yards
Last year--18 receptions for 288 yards
More than a third of his production this year came against I-AA Eastern Washington (126 yards).
That is in the Texas Tech offense, where 5,000 passing yards is the norm for a season.
Admittedly, part of his senior season at Texas Tech was lost due to suspension.
Physically, he is a freak athlete. But if he couldn't put up numbers in Texas Tech's system (or stay in the good graces of their coaches), why would anyone think that he would have put up numbers in Iowa's system?
