Delpit is not in same leagues as Jamal Adams, or even Derwin James. A Safety who cannot tackle is useless, and I wouldn't take him until second round (where he probably won't fall), so is reach at 17 IMO.. IF feel need to take a Safety in Round 1, go with Xavier McKinney, who should be there at 17. Can play FS or SS, can cover and tackle. I am still of the opinion though that Safety is less valuable position than other places. Not that many teams have awesome safeties and Safety is usually NOT the reason you succeed (otherwise the Jets, Broncos, and Steelers would've been better).

I agree that CB is a need so I would go with either Kirstian Fulton or Trevon Diggs in first round, or go for DT Derrick Brown or Javon Kinlaw to help shore up D-Line (another area of need). Then can try to grab an above average Safety in round 2 or 3 (Ashtyn Davis, Kyle Dugger...)
