Back in his early days, St. Pierre was aggressive and took more
chances. His well-rounded talents had carried him to the UFC
welterweight championship, and he looked unstoppable at 170 pounds.
“Rush” was considered by some to be the closest thing to a perfect
fighter, so when Serra won Season 4 of “The Ultimate Fighter” and
an automatic shot at the title, the masses mostly shrugged.
Popular opinion had St. Pierre obliterating the Renzo Gracie
black belt. Even though Serra said and did all the right things,
the odds were stacked against him.
When champion and challenger squared off at the Toyota Center in
Houston, Serra was immediately in St. Pierre’s face. The journeyman
never allowed GSP to establish a rhythm, and before anyone knew it,
a right hand had stunned and floored the
Tristar Gym great. St. Pierre sprung to his feet but was
clearly dazed. Serra tore into him with relentless punches, until
another right sent the champ crashing to his back. The underdog
kept firing until the fight was halted. It remains the most
shocking upset in UFC history.
