5 NFL players who couldn't back up their trash talking 

#3 - Matt Hasselbeck

Seattle Seahawks quarterback Matt Hasselbeck

The Seattle Seahawks and Green Bay Packers faced off during the 2003 NFL Playoffs in a tightly contested game that went to overtime. After winning the coin toss prior to the extra time beginning, Seahawks quarterback Matt Hasselbeck infamously proclaimed, "We want the ball, and we're gonna score."

The Seahawks got the ball due to winning the coin toss, but Hasselbeck most definitely didn't score. He instead threw an interception to Packers cornerback Al Harris on the Seahawks' first possession, which Harris returned all the way for a game-winning touchdown.

#2 - Johnny Manziel

Cleveland Browns quarterback Johnny Manziel

Johnny Manziel was notorious for his arrogance and trash-talking. It worked well for him during his college football career, where he was one of the most exciting players in the country while playing at Texas A&M.

His persona never quite worked for him in the NFL after being drafted by the Cleveland Browns, mainly because of his terrible stat line. He started just eight games, recording a 2-6 record while throwing seven interceptions before being chased out of the league for good.

#1 - Cam Newton

Carolina Panthers quarterback Cam Newton

Cam Newton was nothing short of spectacular during the 2015 NFL season. He was named NFL MVP while leading the Carolina Panthers to a 15-1 regular-season record and an NFC Championship. He began to showboat increasingly as the year went on, claiming he was unstoppable and nicknaming himself Superman.

The Denver Broncos may have taken that personally because they proved to be his kryptonite in the Super Bowl. Newton completed less than 50 percent of his passes without scoring a touchdown, while also throwing an interception, fumbling twice, and getting sacked six times.

To make things worse, Newton has never been the same player since, recording a 30-37 overall record and never even returning to the Pro Bowl, let alone playing at an NFL MVP level.
