Prescott was rising up draft boards before he got his DUI. He wasn't going to be the #1 QB, bc his college system didn't show his passing abilities enough. However, he probably would have been a first to second round pick. He nailed all of his interviews.
Mahomes has good skills but his footwork makes his passing inconsistent. Which means at this point he is Cardale. he could be better, he may not be.
