Xavier McKinney, S, Alabama
Strengths: Play diagnosis, preparation, versatility
Weaknesses: Dive-stick tackling
Another draft, another Alabama safety. 
Each Alabama safety, from Eddie Jackson to Landon Collins to Ha Ha Clinton-Dix to Minkah Fitzpatrick to Mark Barron to McKinney, is unique in his own way. Barron was a linebacker hybrid, Fitzpatrick a cornerback hybrid, Collins a traditional box safety and so forth. Yet each is fundamentally the same: They all have tremendous instincts and anticipation skills thanks to their Nick Saban tutelage, they all play fast (even if their 40 times don’t reflect it), and they all have at least some usefulness at all three levels, from pass-rusher to underneath defender to center fielder.
McKinney thrives as a deep safety, where he diagnoses pass routes swiftly and gets a great break on the ball in the air. He’s also a lethal situational blitzer. His biggest weakness is one he shares with Clinton-Dix: a tendency to come in too hot and whiff on open-field tackles. He also may not be the best matchup defender against speedsters hiding in the slot.
As the list above illustrates, Alabama safeties usually have productive careers as NFL starters. McKinney should be no exception. 
The Giants ranked 31st in the NFL at defending deep passes, according to Football Outsiders. Antoine Bethea (now a free agent) looked like he was running in quicksand, rookie Deandre Baker simply wasnt ready to play, and it may turn out that Jabrill Peppers true position really is “athlete.” Newcomer James Bradberry, a year of experience for Baker and a nice retirement party for Bethea should help. But so should reinforcements like McKinney in the secondary. This is a safe selection of a player who slid a little bit.
