How did we rank the players?

We polled 63 experts to rate each player on a 0-to-10 scale, with 10 being the best regardless of position in the NFL. Ties, as denoted by an asterisk, were broken by determining which player had more ballots with the higher number (If players are tied, the player with three 10s is ranked higher than the player with two 10s. If the tied players had the same amount of highest numbers -- each with two 10s -- we moved to the next number: three 9s beats two 9s).

Here is the full list of voters from ESPN.com, ESPN TV, ESPN Radio, ESPN The Magazine, ESPN Insider (including Football Outsiders and Pro Football Focus), ESPN Fantasy, ESPN Boston, ESPN Chicago, ESPN Dallas, ESPN New York and ESPN Stats & Information.

Jennings defended or intercepted 21 passes last year. Jennings was one of three players over the past three seasons to have at least 20 passes defended or intercepted in a season.
