So, that could be similar to what the NFL experiences on Sunday's sometimes.
Take for instance last weeks Browns vs Packers game. Browns, the worst team in the league, had a 21 to 7 lead going into the 4th quarter. The game started to guide towards the Packers direction in the 4th quarter and the game went into OT with the Packers prevailing and winning in OT.
Same with the SB last year, a tale of 2 halves and close to 2.5 halves.
