Let's Start with the ram's most pressing need, an ILB that can shed blocks and attack at the line of scrimmage and be a tackling machine.
1. Patrick Willis - Ole Miss, ILB 6'2 240 4.6
The Rams Linebackers were constantly getting blown up at the second level by full Backs and offensive Lineman. They Lacked Someone who could tie the opposing offensive line up, thats why the rams draft ..
2. DeMarcus Tyler - NC State, DT 6'2 305 5.3
All season the rams were unable to put consistent pressure on the quarterback. Even though
Leonard Little is playing well he is aging and the rams need someone to pair on the end. They need size too in order to stop the run.
3. LaMarr Woodley - Michigan, DE 6'2 274 4.75
Both
Torry Holt and Isaac Bruce are aging and it seems unlikely that the Rams will resign Kevin Curtis because of defensive needs. The pool of recievers in this years draft is exceptional. The rams also have lacked size at the WR position for some time. They go to the National Champs to help themselves out.
4. Dallas Baker - Florida, WR 6'3 207 4.6
Despite the Emergence of O.J. Atogwe at the end of the season the safety position lacked some consistency this season. Who can forget the picture of LT shanking O.J.'s helmet off. The rams could do with some more depth at this position. Again this position is deep in this year's draft. They go out west, to the land of the Beavers.
5. Sabby Piscitelli - Oregon State, S 6'3 224 4.55
Although the Rams have already drafted a DT it was probably there worst position this year. I wouldn't be surprised if La Roi Glover gets cut and that means the rams need to Draft another run stuffer. Due to a bad performance in the National Championship game his stock drops but, he is still a pretty good value.
6. David Patterson - Ohio State, DT 6'3 285 5.05
This is someone that has been under the radar for a long time due to the poor performance of his team and is somewhat undersized but he has a fast motor and is tough. Kind of reminds me of London Fletcher.The rams find some help again at the linebacker position.
7. Thaddeus Washingtion - Colorado, ILB 5'11 245 4.8
The rams other needs, particularly OL Depth I belive will be met in the offseason by signing some veterans on or keeping the Donut Bros. as backups. The rams will probably sign a rookie free agent WR as well. Hopefully they will get Corey Ivy in as nickel back. He played well two years ago. The Rams will most likely sign a free agent DT as well.
Feel Free to Critique and alter.

I hope they make the right moves and address our defensive needs. Go Rams!
