In the NFL, each team brings 12 Wilson footballs to the game and uses its own. As such, the Patriots' offense uses one set of footballs and those are taken off the field when possession shifts. The Colts then bring theirs into rotation. It is not uncommon for teams to try to alter, however slightly but within the acceptable limits between 12.5 and 13.5 pounds, the ball that is most agreeable to their quarterback. So if New England was actually using an illegally inflated ball, it would only help their offense and not hurt the Colts' offense.
