Defensive end has become a more important position in 3-4 defenses in recent years (for elaboration, read this). A 3-4 defensive scheme is built primarily to stop the pass, though stopping the pass stems from first stopping the run. That’s the chief job of the ends. Here are the Top Seven 3-4 defensive ends in football.

7. Justin Smith, 49ers

Not a prototype for this position, but he’s a player who does everything well.

6. Aaron Smith, Steelers

Headlines Pittsburgh’s potent three-DE rotation.

5. Ty Warren, Patriots

Underappreciated in the shadows of Richard Seymour and Vince Wilfork; plays with splendid all-around technique.

4. Glenn Dorsey, Chiefs

Hasn’t really played the position until this year, but based on what he showed last season, he’ll be challenging for the No. 1 ranking by 2010.

3. Luis Castillo, Chargers

When he’s healthy, there isn’t a more disruptive source of energy.

2. Haloti Ngata, Ravens

Has surprising quickness for a man with such power.

1. Richard Seymour, Patriots

A future Hall of Famer. The more someone knows about football, the more they admire the ninth-year pro.

Also considered: Kendall Langford, Dolphins; Shaun Ellis, Jets; Marcus Spears, Cowboys
