im a big believer in SRF and personally would have him at 2 but his delivery is far from clean, particularly with red flags in his high elbow and somewhat herky jerky nature... i believe this is the primary reason he fell so much in the draft
I hate to sound like a broken record, but I think a guy like Mickey callaway could turn Sanchez into a stud. I wouldn't be surprised to see him blossom with a few mechanical changes. But with the way he is right now, he's a good not great RP
