Coples scares the crap out of me. Not only is he a high risk potential high reward (even moreso than Tannehill), but in 2010 when he had success he was primarily a DT, then in 2011 he switches over to DE and utterly fails against ACC competition. I would rather pick Andre Branch with the #8 overall pick than Coples, at least he had success at DE against the same competition. (no I'm not serious about Branch at 8, im not stupid) If I were to grade the prospects by ceiling and floor at the DE position this is how it looks.
Ingram: Medium floor, high ceiling
Coples: Low floor, high ceiling
Jones: Low floor, high ceiling
Mercilus: Low floor, extremely high ceiling
Perry: Medium-high floor, high ceiling
Branch: High floor, high ceiling
Curry:Low- Medium floor, highish ceiling
everyone has their opinion, but dont come crying to me when Coples busts hard, and some of these other guys succeed. Also keep in mind that we could possibly get Branch or Curry in round 2, which makes the floor even higher. All of the guys I listed have "first round grades".
