If Tebow could run like Nick O'Leary at FSU he might better his chances as a TE.
If Nick Marshall could tackle like Jack Lambert of the Pittsburgh Steelers, it might better his chances at middle LB.
But, on the other hand, if Nick O'Leary could jump and dribble like Lebron James, there could be a legitimate shot at his getting drafted into the NBA.
If Lebron would work at learning how to ride a horse like Gary Stevens or Pat Day, he may be able to become a jockey. If he has 4-5 feet of his legs removed, of course.
