In order to win the Superbowl, you need the best O-Line/D-Line combo in the league. The battle up front is easily the most important to the team -- because they're there every single down. I'd list all of the super bowl champs here, but honestly I'm lazy and you can go to wikipedia for further investigation. Bottom line is every single team who's even been in the super bowl in the 2000's has had this. So I suggest before we jump the ship on either Sanchez or Revis, we take care of the heart and guts of the team--the linemen.
