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 highest number. (If players were tied, the player with three 10s was ranked higher than the player with two 10s. If the tied players had the same amount of the highest number -- each with two 10s -- we moved to the next number; three 9s beat 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.

Witten set an NFL record last season for the most receptions by a tight end (110). He eclipsed the 1,000-yard mark for the fourth time; Witten and Tony Gonzalez are the only players to do it that many times at the position.

San Francisco 49ers | OT | Age: 28 | NFL experience: 7th year
ESPN Fantasy rank: 49ers' projections

Percy Harvin | @Percy_Harvin
Seattle Seahawks | WR | Age: 25 | NFL experience: 5th year
ESPN Fantasy rank: WR89

When healthy in 2012 (Weeks 1-9), Harvin had 528 yards after the catch, which led the NFL and was 154 yards more than Wes Welker, who ranked second over that stretch. Despite playing just nine games, his 528 YAC still ranked fifth for the entire season.

Health is a skill. It's one of the skills that Harvin hasn't mastered, making him overrated on this list.
