Mark Sanchez's effort to hold off Tim Tebow could be doomed by Jets' supporting cast

CORTLAND, N.Y. – Jets fan No. 1: "I should probably get a picture of [Mark] Sanchez. He is the starter."
Jets fan No. 2: "Sanchez is a lot better but you wouldn't know it. The offense is so atrocious. See that scrimmage? Looked like Cortland out there. They'll probably put [Tim] Tebow out there and just say 'Run for your life.' "
Mark Sanchez gets sacked during last Friday's preseason game against the Bengals. (AP)Ah, Jets fans. The painful eventuality these jaded folks feared entering training camp went something like this: The pressure of Tebow's popularity would overwhelm Sanchez, and he would crumble while the Chosen One ascended.
That hasn't happened … yet. Sanchez looks strong. His throws have zip, he has better pocket presence, and he's a leader in a way he hasn't always been in the past.
"He's letting his feet talk to him," raves backup quarterback Greg McElroy. "He's not holding the ball for a certain route. He's done a great job of working with the protection and working with Nick [Mangold] up front. He's done a great job of getting better."
But Tebow's likely going to end up starting at some point anyway.
The problem is not Sanchez; it's the offense. That was clear Wednesday morning as balls got tipped, picked off, dropped, or simply left to hit the ground.
