After Leinart and Bush are off the board my attention would go to
Ahmad Brooks over AJ Hawk. Here is what they say about Brooks from nflfans.com
Pros: Great size, speed, jumping ability, and elite athleticism - the whole package when it comes to physical attributes. Terrific coverage and pass rushing skills. Sideline to sideline type of linebacker that can chase down the fastest of running backs and cover TEs and RBs well. Very hard hitting while being a good wrap-up tackler as well. Good at stuffing the run up the middle. Trained in the 3-4 scheme under Al Groh (former Parcells/Belichick protege) so should be able to come in and start immediately for any 3-4 team. With his speed, athleticism and pass rush skills, should be able to handle any LB spot inside or outside. Can take over a game with his defensive play.
Cons:Had minor knee surgery during the offseason, came back and sprained his ankle. Returned out of shape and not fully healed from ankle sprain. Not producing much this past season because of injuries because he's only played in about half the season. Questions could be raised about his work ethic from this past season. Although a disciplined player for the most part, tends to freelance once in awhile. In 2003, was caught with marijuana but no other reported incidents since.
I seriously think he will be joining the draft this year. Also since he is having a off season this could drop him to the 10-15 mark in the draft.
On another note I would not draft Ngata that early. He seems to be lost on the field and also takes to many plays off. I just do not see the desire to be the best playmaker when I look at Ngata.
