1. I would give up a first round pick. He would make our offense the greatest all-time.
Pros:
Can block, catch, and get the tough yards. He will be in his prime for 3 more years, and average frist round picks have contracts of 4-5 years. Seems like taking an All-Pro for 3 years make more sense than grabbing a rookie who may or may not turn out for 5 years. Will dominate in winter.
Cons: Takes away salary cap space from more important positions (defense, offensive line). Takes the ball out of A-Rod's hands more often. Has a lot of mileage. Smart, but opinionated player.
2. See above.
3. Players I'd give up two first round picks for: Joe Thomas, Pierre-Paul, Revis, Calvin Johnson.
