Ok, this is what I would do, swap # one picks with Baltimore (dont get me wrong, I love Roy Williams, but he cant cover), also Baltimore has to throw in a # 3 or 4 round pick also, along with Ed Reed and Ray Lewis. In return, we give them Roy Willliams and Greg Ellis. Then, possibly we trade Ray Lewis for a 3rd rounder to a 4.3 defense, somone not in our defense, say Bengals as an example.
Then, we trade back down in draft, get an extra 2nd or 3rd, along with a 5th or 6th pick.
That would give us, say 15th to 20th pick in draft, right in front of 49ers and Giants, whom both want linebackers.
# 15th to 20th pick
# 2
extra # 2 or 3 trading down wtih someone for our 13th pick
# 3
extra # 3 or # 4 trading with baltimore
# 3 extra 3 for trading Ray Lewis to someone like Bengals
# 5
# 5 extra for trading down
# 6
# 7
That would give us 5-6 players in top 3 rounds, maybe along with a 4th rounder we dont have. You would still be able to get Manny Lawson or Bobby Carpenter, along with 2-3 extra draft picks in top 100.
Only weakness we would have is veteran leadership on defensive line for losing Greg Ellis. It takes defensive linemen 2-3 years to learn playing defensive line.
