What if the Pats-Colts game ends in a tie? It does happen once in a while, it’s a possibility. But of course in the end it doesn’t matter, play better football. And some of this stuff is overblown anyway. In the Dallas game Dallas called a timeout in the final two, if they hadn’t done that time would have expired before the last play went off. In the Miami game the Phins were down 21 and at the exact same time the Texans were erasing a 29 point deficit, and lets not forget week 4 Chicago and Detroit, then there’s always Heidi. No lead is safe in the NFL, stack up the points until the gun.
The odds of those two teams going 15 minutes in a dome without points, each knowing they only need a field goal, are so remote as to be not worth considering.
