"The history of sports is rich with boastful athletes who backed up their considerable trash talking with unforgettable results. Who could forget Mark Messier and Joe Namath backing up their guarantees, Muhammad Ali proving that he really might have been the greatest and Babe Ruth calling his shot? Watching a scenario in which being cocky turns to into exhibiting well-founded confidence ranks as one of the great lures of following sports.

Of course, the flip side to victors writing history is that the many braggarts' failures are erased with time.

Sure, we do hold onto some special moments when high-level hubris explodes in a player or team's face in a hilariously spectacular way. Anyone who heard Matt Hasselback shout "We'll take the ball and we're going to score" probably cannot forget the pick-six he threw in that same overtime contest.

Even in that example, it was a little bit tolerable since Hasselback was the Seattle Seahawks' top quarterback and one of the best players on that team. He could either walk the walk or stumble along the way in that situation, so the fact that he fell on his face was made that much more memorable.

It's a lot more frustrating for a team when an "outsider" of sorts throws that extra burden of pressure on their shoulders. Vince Young basically called the failing Philadelphia Eagles a "Dream team" the second he joined that squad."
