It's becoming clear that Sanchez isn't improving as a QB, I thought there was some improvement last season, but he's missed receivers all over the place when he's had time, rarely makes a play, and the Jets don't have offensive playmakers.
The QB controversy is going to be loud this week, and Sanchez is responsible for that. He's been a disaster today, WR's have missed many balls as well, but Sanchez has had chances and hasn't made plays when he needed to.
4th years QB have to show improvement, and it's just not there. Maybe he turns it around later in the season, but the window is closing quite fast on Sanchez as a starter.
