Quarterbacks can make or break a team in the NFL.
Teams put time and money into their quarterbacks and expect big results from their leaders. Unfortunately, fans are disappointed by quarterbacks every year.
These quarterbacks that are sure to disappoint in 2012 range from stars to unproven players looking to make a new for themselves.
Ben Roethlisberger is going to have to make big adjustments in 2012 with Todd Haley as offensive coordinator.
Unfortunately for the Steelers, Roethlisberger and Haley are already off to a rough start. Having a completely new offense can be frustrating and mess with a quarterback's head.
Also, Roethlisberger has other obstacles to overcome besides learning a new offense. Roethlisberger is injury prone, and Mike Wallace is a no show at Pittsburgh's OTAs.
With big change, injuries and Roethlisberger's best weapon having his status with the team still up in the air, Big Ben will be disappointing the Steelers fans in 2012.
Matt Flynn will finally get the chance to be a regular starter in 2012.
The Seattle Seahawks took a big risk by signing Flynn to a three-year, $26 million deal. The quarterback dominated the only games he has ever started, but he's very unproven.
Yes, Flynn looked like a future star when he tore up the Detroit Lions for 480 yards on 31-of-44 attempts and six touchdowns. That was with the Packers and not the Seahawks and doesn't make someone an instant star.
However, Pete Carroll has already praised rookie, Russell Wilson, and put him in competition with Flynn and Tarvaris Jackson.
Flynn is already being questioned as the Seahawks' starting quarterback and will soon realize the Seahawks are not the Packers.
Sam Bradford is in for another long year in 2012.
The St. Louis Rams didn't have the proper weapons for Bradford to excel in 2011. In the draft, St. Louis failed their prized quarterback by not getting enough weapons for him.
The Rams had no outside weapons for Bradford in 2011, and Brian Quick and Chris Givens were not the right answers. Stephen Hill, Alshon Jeffery, Ryan Broyles and Rueben Randle were all taken in the second round after Quick. All picks were better options than Quick.
Bradford is another injury-prone quarterback and doesn't have the proper weapons to throw to, which will ultimately disappoint the Rams once again in 2012.
Ryan Fitzpatrick was a completely different player in the first half compared to the second half of the season.
Fitzpatrick had a stellar start to the season that earned him a new six-year, $59 million deal. Unfortunately, Fitzpatrick didn't earn his money in the second half of the season.
The Bills went 1-8 down the stretch of the season and Fitzpatrick threw 10 touchdowns compared to 16 interceptions. Buffalo acquired Vince Young to back up Fitzpatrick this offseason in case he has another collapse.
Fitzpatrick hasn't been consistent enough throughout his career and will disappoint the Bills in 2012 by not living up to his hefty contract.
Matt Moore will dearly miss Brandon Marshall in 2012.
The Dolphins quarterback progressed as the season went on, giving fans something to smile about. However, the Dolphins still drafted Ryan Tannehill with their first pick to eventually take over for Moore.
Unfortunately, Tannehill may be thrown into the fire earlier than expected.
Moore doesn't have the outside weapons to be successful and will be inconsistent in 2012.
Let the drama begin for the New York Jets and Mark Sanchez.
Bringing in Tim Tebow will not do wonders for Mark Sanchez and his confidence as a quarterback. Let's be honest, Tebow was not brought in to be the punt protector.
The first mistake or rough game Sanchez has, fans will be begging for Tebow. Rex Ryan has stayed loyal to Sanchez, but if No. 6's completion percentage hovers around 56 percent again and he is losing games, Ryan will be forced to make a change.
The Jets have to make the playoffs in 2012 and can't let Sanchez ruin that.
Sanchez will disappoint fans with his inconsistency, bringing Tebowmania to New York in 2012.
