Delpit at #17... ehhh. He'd be a 5 year starter at a position we have sucked at forever, so you can't be too upset about that, but he wouldn't bring the same kind of wow factor that say Kinlaw or Chaisson would. With those guys, you're looking at Pro Bowls if everything clicks. Delpit looks more like a steady Eddie who doesn't have that kind of upside.
Xavier McKinney is the same way, I just like McKinney more because I love his versatility and hate Delpit's tackling. McKinney would be a really strong fit in our new quarters defense that asks safeties to handle a lot of different assignments. So if I'm picking a safety at #17, I'm going for him over Delpit, but even as this board's biggest McKinney cheerleader I'd feel a little let down.
Davis is a guy who has all the physical tools but doesn't have much instincts. He has an alibi in that he was a track guy who started football late, so maybe he just needs to spend some time with coaches learning how to break down route combos and read QB's eyes and such. The bet you're taking is that your coaches can teach him that.
I'm not making that gamble in the 1st round with Delpit, McKinney and Winfield all looking like they were ready to play in the NFL yesterday. In the 2nd though, I'm more amenable. 75% of those guys are going to bust anyway, so they're all dice rolls at that point. Davis is a hard-hitting 4.4 safety with ball skills if he makes it.
