I am kind of puzzled by people who characterize Sanchez as overrated. By whom is he overrated? How many times has somebody listed him as one of the top ten quarterbacks in the league? If this has happened, I have not seen it.
A while back, I rebutted the notion that Sanchez's stats tell the whole story of his play. KC Joyner of ESPN two weeks after I wrote that piece posted something that fell into all of the talking points I preemptively rebutted. Even so, saying Sanchez is better than Henne is not saying much.
I think Mark is an interesting guy to evaluate. A lot of guys would probably have at least as good of a win-loss record with the supporting cast he has. When he has gotten to the Playoffs, Mark has been a big reason the Jets have won. They simply do not beat the Patriots in Foxborough without an excellent outing by Sanchez. In his first career Playoff start, Mark hit 12 of 15 and had two balls his receivers should have caught.
Sanchez is kind of the opposite of Joe Flacco. Flacco is a guy who puts up great numbers but tends to disappear in big games. Unlike Mark, Flacco has played poorly in the postseason. His team's success has been more about other guys stepping up. As Sanchez gets more consistent with age, I think he will become easier to evaluate.
