Calvin. Rodgers has shown his ability to distribute to everybody within the offense. While Jennings will improve on last years numbers, Finley should emerge as another threat and Jennings will never be the possession WR that Calvin can be. As Stafford develops, he will rely on Megatron. With Orlovsky and Culpepper throwing to him, Megatron put up 1300 yds. Imagine what he can do when Stafford comes around (which I believe he will). Enjoy Megatron and Rice and don't look back. You got 2 stud keepers for the next few years.
Calvin, Detroit is only getting better. Packers are a great/young offense, but I cannot see them being that much stronger on offense. That its even a question given their two situations speaks to how talented CJ is....
