Even so, there are legitimate concerns such success won't translate to the NFL. Pittsburgh Steelers personnel director Kevin Colbert said Tebow would need one to three years adjusting to a pro-style offense after playing in a spread system at Florida. Sirius NFL Radio analyst and ex-NFL quarterback Jim Miller is concerned that Tebow will revert to old habits - like holding the football too low on his wind-up - when under pressure in games. Miller played for Chicago in the late 1990s when the Bears unsuccessfully attempted to change Cade McNown's sidearm throwing motion.
"They tried to get him to become more accurate by throwing over the top and he just couldn't do it," Miller said. "He spent the whole offseason working on it, then lo and behold, everything went to crap on the first day of practice. He threw the way he always threw.
"For Tim, it's not just the motion or footwork involved. It's everything."
