A couple of weekends ago, a friend of mine – a serial sports bettor – called to relate to me his latest mood-altering, stomach-turning, I-bet-the-house-and- had-the-house-won- until-the-house-came- tumbling-down wagering disaster: He bet $1,000 on USC as a 7½ - point underdog against Stanford. USC never trailed by more than seven points and even led late in the game but Stanford forced overtime. If this were the NFL, my friend would’ve been ensured of winning his wager, since USC could not have lost by more than six points in the sudden-death extra period. But in college, teams alternate possessions from the 25-yard line, and if the game remains tied through two overtimes, by rule teams must try a two-point conversion from the third overtime on if they score a touchdown.
