Sanchez is young and brings little experience to the table, but he is talented. The Jets played the Ravens on monday and, well he didn't look horrible.
He threw a pick six but did bounce back and throw a TD. Coach Rex Ryan spoke about how he liked the way Sanchez bounced back. To his credit not many veteran quarterbacks have success against that defense.
When you take someone with your first pick and pay him all that money, fans want to see him play, especially when he has the talent to be a starter.
NY is a rough place to play, if he gets off to a good start the fans will get behind him. If not...good luck...
