Fantasy football DEFENSIVE PLAYERS help?

First i think that Patrick Willis and D.J. Williams are two good picks for linebackers. They get alot of tackles and a few sacks. But i think Elvis Dumervil out of Denver is a great pick. He had 12.5 sacks last year and should get even more this year. He also forced 4 fumbles, and had 39 tackles. He is a great d line pick. Also a secondary pick is Champ Bailey. He had an off year and still had 3 picks, 17 pes defended, and 84 tackles (71 solo) . He would have had about 150 points on that method of scoring. He should do even better this year and be back up to the top shelf of all defensive players.
