The demise of the Denver Broncos in Super Bowl XLVIII can be blamed on many things, but perhaps the crucial turning point came before the game even started.
This is because former NFL great Joe Namath hilariously botched the coin flip by not giving the Seattle Seahawks a chance to call heads or tails.
Namath's ensuing flip resulted in a tails, which hadn't happened in the previous five Super Bowls, and ultimately gave the Broncos the choice to take the ball first. As you know, Denver was doomed from the first play.
