IMO helping your biggest rival get better is just a bad move. I understand the goal of the draft is to improve your own team, but you can do it without helping the team that's won 3 of the past 4 Super Bowls.
This years draft, the Bills trading with the Chiefs reminded me of the days when it seemed teams got in line to help the patriots get better.
It's done now and the guy we let the Chiefs have scored two TD's in his first NFL game, I'm sure Andy Reid said thanks again Buffalo.
