If you know anything about Belichick's draft board strategy, it is much simpler than with other teams. He only keeps 25-30 players on the entire board. If a player does not meet height/weight and speed requirements, he is taken off the board.
If the player does not meet mental requirements, he, too, is taken off the board.
With that in mind, the Saints can afford to be picky. Players such as Jarvis Jones, Ezekiel Ansah and Sheldon Richardson are all great prospects. None of them, however, fit the style of defense that Rob Ryan is going to play in 2013 and likely beyond.
For that reason alone, those players should be left off the Saints' draft board altogether. There are 10 players who should fit atop the Saints' draft board based on team needs and overall ability.
