I guess there is a reason why you aren't managing a team in the nfl ? So you would trade say a Mario Williams and Kyle Williams straight up for a backup Qb named mark sanchez.
You do realize that during the two seasons that the Jets made the AFC championship, they had a top 3 defense and one of the better running games in the NFL? The subsequent seasons when they couldn't rely on those , and had to rely on Sanchez''s arm instead , they didn't do so hot.
