As a Jets fan, I can tell you this: Tim Tebow IS being blackballed... ...because he’s a quarterback who can’t throw the ball.

He does have a noticeable hitch in his throwing motion that makes him vulnerable to fumbles. I remember watching videos of him working on changing that motion after college and just before the NFL draft -- but I don't think he was successful in doing so.

He holds the ball too low.

Here's a recent article claiming Tebow's fixed his footwork and is throwing much better now.
