They'll be wrong. Let them be wrong. The more decisions you make the greater likelihood of flubbing the bottom line...
Greatness finds a way. That's my amusement with all the knocks on Manziel's playing style. Do you really want to be among that crowd, the ones who think he'll fade to mediocrity or worse simply because the NFL is more pocket oriented? Scary. Absolutely scary. There's a guy with all this early demonstrated talent, good enough to shred Alabama twice, and you are relying on an adjustment and little else. Good luck with that. Manziel drops back, scans the field, and suddenly the adjusters are terrified. Wait a minute. He completed a dart from the pocket. And he didn't act surprised or winded or even slightly impressed with himself. How can that happen? What about my cynical adjustment? The freak talents have no trouble adapting.
The same crowd who want to pretend a moderate talent merely needs more time are generally the ones who happily downgrade the genius types.
When Manziel became prominent midway through the 2012 season, I did some research and found the high school article in which he emphasized that he was determined to be a good person off the field. I posted that link here last fall. As always, I place highest value on early indications, not last second cramming for tests. I believe Manziel will live up to that promise.
