Yeah. Give them another 15:00 minute quarter. The team with the lead at the end wins. Maybe give each team one timeout.
During the regular season, if neither team gets the lead, it ends in a tie, and during the playoffs they add on another quarter until someone wins. This could cause hell with the networks, but that should be secondary to the integrity of the game and the players.
It's sure going to be a boring Superbowl this year. I guess we'll have to make it interesting by cheering against the Seahawks.
