You win some, you lose some.
I had Northwestern -6.5 against Stanford. NW down 10-7 with :30 left and the ball at their own 20ish. I'm counting my winnings. NW QB rolls left gets pile driven into the turf, fumbles and ball rolls back into the end zone where a NW lineman could have easily fallen on it for a safety but somehow can't collect the ball. Stanford recovers in the end zone for a TD. Brutal beat.
A few hours later I have Auburn - 2.5. Had no business covering that game but somehow did. Crazy.
