Devin McCourty, the New England Patriots rookie cornerback, is very good at football. His team-leading seven interceptions (second-best in the NFL), 82 tackles (third on the Pats) and overall quick development into a shutdown corner helped the team's defense improve every week throughout their 14-2 season.
↵Another number that gives you an idea of how special McCourty is: in just 20 yards, he can run 19.6 mph, the fastest speed recorded at the Sports Science lab.

And don't worry about him going backwards -- he's still 80% as fast.
