I'm a big proponent of evaluating NFL prospects by what they do on the college football field against high caliber opponents. It's not 100% accurate, but it is better than basing it on combine performances. Both the SEC (Mcelroy and Tebow) and PAC 10 (Sanchez) are top conference, with the SEC being the best in the country top to bottom. Here is how the Jets 3 QB's did in their final college seasons.
Sanchez 241/366 65.8% 3207 34/10 8.8ypa 164.6
Tebow 213/314 67.8% 2895 21/5 9.2ypa 164.2
Mcelroy 222/313 70.9% 2987 20/5 10.1ypa 169.0
Even in college Sanchez was the most interception prone, and he was even less accurate than Tebow
Big Mac (that's what I'm calling him now) had by far the highest completion percentage and ypa meaning he wasn't dinking and dunking the ball all the time.
Every opportunity Big Mac has had, he has performed. Whether at Alabama against the cream of college football, or even in the pre-season against NFL scrubs, the guy has answered the bell. It is time to figure out what the Jets have... a career back-up or a starting caliber NFL QB. Face it, the Jets right now are winning club if the QB completes 60% of his passes and stops turning the ball over so much. Mcelroy could be that guy, but we'll never know unless he is given an opportunity.
