With Sanchez under center, the Jets are a lowly 3-6 and sit at the bottom of the AFC East.
Sanchez has been horrific—in nine games, he has thrown for only 1,860 yards, 10 touchdowns and nine interceptions, giving him a 70.4 quarterback rating.
Despite his quarterback completing only 52 percent of his passes, Jets head coach Rex Ryan has adamantly defended Sanchez at every possible turn, claiming Sanchez gives his team the best chance to win (h/t ESPN):

Ryan's defense of the quarterback he brought in is admirable, as both are in serious danger of losing their jobs. For Ryan, taking a chance with a backup at this point could at least save his job.
On the other hand, Sanchez's job was in question before the season even started and well before the Jets organization elected to bring in the most polarizing figure in all of sports, backup quarterback Tim Tebow.
While Tebow has been reserved to gadget plays and acting as a punt protector on special teams, many have been clamoring for him to take the starting role from Sanchez.
At this point, naming Tebow the starter makes more sense. He can at least complete 50 percent of his passes and is a threat to run the ball on every down as well. Sanchez has no traits that make defenses account for his running ability, which makes it easier for defenses to focus on the pass.
To be fair, Sanchez isn't the only one losing his job after the 2012 NFL season. The entire coaching staff is likely gone as well, including the plethora of mediocre offensive coaches.
Sanchez has had no help from his running game either, as running back Shonn Greene has been horrible. The lack of support in that area has killed Sanchez, as opposing defenses don't care enough to stack the box, which results in more difficult defenses for Sanchez to diagnose.
Adding to Sanchez's woes is Tebow. Not because Tebow is a good quarterback, but because the coaching staff insists on removing Sanchez from a game any time he begins to find a rhythm so that Tebow can come in and run a play.
A two-quarterback offense in the NFL doesn't work, and New York is now the most recent example of why it fails. Sanchez cannot get into a rhythm, and when he does, he has to run to the sideline in the middle of a drive for the sake of Tebow instead of continuing a positive offensive series.
With a competent coaching staff in place and a talented supporting cast, Sanchez may be able to play at a starting NFL quarterback level, but that won't happen anytime soon in New York.
The current coaching staff is likely on the way out, which means Sanchez is as well. There's some serious rebuilding needed in the Jets roster, and Sanchez will likely be the first piece removed from the equation.
Quarterback is always the first position to get blamed in a situation similar to the one in New York. The Jets are in a position to have a high draft selection, which will likely be used to find a new franchise quarterback with a new coaching staff wanting their own guy.
There's always the outside chance the Jets will go with Tebow in 2013, but a shiny new draft selection will likely be taking things over.
Sanchez didn't necessarily get a fair shake in New York over the past four years, but that's the nature of the business. He's not an NFL starting quarterback, and he certainly won't be the starter for the New York Jets in 2013.
