Editor's Note: This package was published in the spring of 2013, and doesn't include any players drafted after that point.

This year represents the 35th anniversary of Mel Kiper's NFL draft guide. To celebrate, Mel combed through his guides and found the prospects with the best grades, separated by position. Remember: These grades were given before the players were drafted, and do not do not reflect players' performance in the NFL. No player who was drafted before 1979 is eligible.
