70. Ahmad Black, Buccaneers 51/100

Coverage: 25/40, Run Defense: 4/15, Tackle: 8/20, Speed: 14/25

A small free safety with limited range, Ahmad Black doesn’t bring much pop in the run game or as a tackler. Black does well in coverage if he’s in a zone, but when put in man coverage, he’s not big enough or fast enough to make positive plays. Black will limit scores and does a good job securing tackles when in position. There’s upside here for Black as a backup safety.

69. Craig Dahl, 49ers 51/100

Coverage: 22/40, Run Defense: 4/15, Tackle: 7/20, Speed: 18/25

Missed tackles were a problem for Craig Dahl last season, as he struggled to maintain contact and bring down ball-carriers. Dahl didn’t show up in run support and was a weak link there too. Dahl does have above-average speed and can track the ball in coverage. He allowed just one touchdown in coverage, but he was beaten up underneath for catches and yards after the catch. Dahl didn’t surrender big plays over the top, but opposing quarterbacks picked him apart for chain-moving plays.

68. Danny McCray, Cowboys 52/100

Coverage: 20/40, Run Defense: 5/15, Tackle: 6/20, Speed: 21/25

A starting strong safety for Dallas throughout much of the season, Danny McCray had his ups and downs. As an athlete, there’s potential here. McCray shows good speed in getting from Point A to Point B in coverage. He doesn’t show great reaction time to the run and can struggle with identifying where the ball is. McCray isn’t a strong tackler, and he will give runners a second chance with missed tackles.

67. Matt Giordano, Raiders 53/100

Coverage: 21/40, Run Defense: 5/15, Tackle: 7/20, Speed: 20/25

Raiders safety Matt Giordano has very good speed and range for the position, but he gets caught up in the fundamentals of the game. Giordano isn’t a strong tackler. He’s able to fly into the box to make plays, but he doesn’t have the tackling skills to bring down runners. In coverage he’ll allow a lot of receptions when targeted. Giordano is a player who gives up too many scores for the number of times he’s matched up against in coverage.

Last year's ranking: 29.

66. Antrel Rolle, Giants 53/100

Coverage: 17/40, Run Defense: 8/15, Tackle: 8/20, Speed: 20/25

Giants fans will tell you that Antrel Rolle wasn’t used right in 2011 and 2012. But in both seasons, we saw an overrated player struggling in coverage (man or zone) and in run support. Rolle allowed over 72 percent of passes thrown his way to be completed, giving up over 10 yards per catch. Add in the yards after catch due to his many missed tackles, and it’s easy to see why Rolle has ranked so low in each NFL 1,000 series.
