Walter Thurmond had has a significant history of injuries, but he graded out as Pro Football Focus’ 31st ranked cornerback last season on just 480 snaps. He dominated on the slot, ranking 7th in the NFL among eligible cornerbacks, allowing 0.85 yards per coverage snap on the slot on 229 snaps. For that reason, I was worried someone would overpay him as an above average starting outside cornerback. He’s still an injury risk. There was still no guarantee that he could be as dominant outside. And there’s still no guarantee that he’d be the same play outside of Seattle’s system, without Seattle’s pass rush in front of him, and without the rest of Seattle’s secondary around him.
That being said, the Giants were really wise to give him just a one-year deal, worth just 3.5 million. Worst case scenario, they’re not out of a lot of money. Best case scenario, the Giants have a great value on a high level cornerback for a year. He’ll man the slot in between Dominique Rodgers-Cromartie and Prince Amukamara. The Giants now have a very solid secondary all of a sudden. They’re playing free agency very well, waiting for the off-season to come to them (with the exception of overvaluing Jon Beason).
