Two picks after selected CB Richard Sherman, the Seahawks used their 2nd 5th round pick on Mark LeGree, a defensive back out of small-school Appalachian State. LeGree is a Walter Camp FCS All-American selection and had a ridiculous 22 picks in his career at ASU. At 5'11, 210 he's not a safety in the Kam Chancellor mold, but he's got decent speed and according to scouting reports, demonstrates a good ability to diagnose the run, recognize routes, read the QB's eyes, and is a leader on the field.
As you can tell by his FCS leading 22 picks, LeGree is a ballhawk. I'm not really sure where he fits in at this point but he's versatile enough to play strong safety next to Earl Thomas or bump over to corner in a pinch. He's got through the roof ball skills for a defensive back and tracks the ball well in the air. Just watching some highlight tape, he seems to be a pretty good thumper in the run game defense as well. Keep in mind he's approximately the same size as Lawyer Milloy so the Hawks could be drafting him as a successor to the veteran strong safety.
LeGree's timed straight line speed of 4.56 in the forty isn't eye popping but was actually 2nd best of any safety at the combine and his short shuttle of 4.09 is elite. It should be noted he also finished 2nd in the 3-cone (6.09), 2nd in bench (22 reps), and 4th in broad jump (9.8"). So yes, he's athletic. If he can translate some of his ballhawking ability to the NFL level, the Seahawks' defensive secondary just got a little scarier to opposing quarterbacks.
As for value, I'd say that the Hawks got him about where he was expected to go, if not a little later. Some outlets had him rated as high as the 2nd or 3rd round due to his Combine numbers, but I'd say the consensus was 5th/6th rounds so overall I'm not disappointed with his selection here.
