I agree that Shawn Merrimen would be a mire desirable player to go and get. I feel that pass rush along with pass protection is the 2nd most valuable asset to a football team. QB being the first. However, Antonio Cromartie would easily become Green Bay's No. 2 corner. He's still very young which fits into the mold of this team and his experience in the 3-4 is a plus. He has a lot of talent. He's as talented as any corner in football minus Darrelle Revis and his cousin Dominique Rodgers-Cromartie.
You get him and this allows you to bring Al Harris back slowly from his injury, but when he does come back, he can go to being the nickel back which is pretty much a starter in this defense anyways considering how much nickel Dom Capers likes to play. It also bumps Tramon Williams to the dime back.
That's quite the upgrade one player could make.
I'm guessing a second round pick gets it done. He may even go for less. Actually, probably less.
My guess is San Diego will get Vincent Jackson and Marcus McNeil locked up long term this off season. I think you could see them part ways with Cromartie and Merrimen. They've drafted replacements for both of those players in Antonie Cason and Larry English.
Again, I'd prefer Merrimen, but I wouldn't rule this out either.
