Sanchez was benched in a loss against the Arizona Cardinals, survived a poor performance in a win against the Jacksonville Jaguars but then threw away the Jets season and his starting job in a disgusting loss against the Tennessee Titans.
With Sanchez down for the count, everyone has now been lining up to kick him.
It's easy to beat someone while they're down, especially with a five-turnover game against a poor NFL team fresh in everybody's minds.
But there were good times too.
In fact, Sanchez has given Jets fans some of the greatest moments in franchise history.
From their back-to-back AFC Championship game runs to a number of late-game rallies, if you view Sanchez's tenure as a Jet as a whole, the Jets have had much, much worse from the quarterback position.
If Sanchez never plays another down for the Jets, he will leave the team with a 33-28 record. By comparison, Chad Pennington was 32-29 and Vinny Testaverde was 35-26. The only difference is that Sanchez also had a winning playoff record while the other two didn't.
In fact, Sanchez's four playoff wins are twice as many as any Jets quarterback in their history, including Joe Namath.
Sanchez's place in Jets history will be tough to judge. If you flipped his career around and he finished with two AFC Championship game appearances instead of starting with them, he'd go down as one of the best Jets quarterbacks in their history.
But that's not how things work.
Things are ugly now and the good times seem long ago. However, there are a number of franchises around the NFL who could only wish to have the success the Jets did with Sanchez at the helm.
Sanchez has taken a beating for most of this season and the vitriol reached its maximum this week, and deservedly so.
But when you take a step back and look at the good times from the past four years, things weren't always that bad.
Here's a look at Mark Sanchez's ten best moments as a Jet.
