Tebow wasn't on an NFL roster last season because he's not an NFL quarterback. It's really that simple. Many of us have said this for years.
He certainly isn't the first guy to win a Heisman Trophy as a running quarterback in a fast-paced offense that is well suited to the college game, only to turn into a bust in the NFL.
He's actually a tremendous athlete and would probably be an All-Pro candidate for much of his career if he had played a different position.
Some people just won’t listen to reason, but you are of course absolutely correct. Tebow’s skills just didn’t translate to the NFL. It happens.
