It does look like Upshaw and Coples are in a free fall. While Mayock says he wouldn't touch Coples in the draft in any round, I think he still may go in the middle of round 1 but there is no way he sees the top 15.
Upshaw just has too many physical limitations to go round 1 although his instinct is top notch. I think he now slids to round 2.
I really think McClellin and Jones go round 1 towards the 25-32 range. McClellin has the college production and his workouts have shown he has the physical skills to be solid at the next level. Jones is also coming on strong as a possible 4-3 DE who can play at 280-285lbs. or a 3-4 OLB or DE depending on which team drafts him.
