IF Tebow committed to a position change -- TE or RB -- he'd be more marketable. As it is he insists on playing QB -- and there's enough NFL tape of him at QB to show exactly his strengths and weaknesses.
Which means: Not much market.
Personally, if I were a GM and had Blaine Gabbert as my QB, I'd be on the phone w. Tebow. Because Tebow can win more games than Gabbert just like he could have won more games than Sanchez last year. And chances are, with Tebow playing QB and ball control, Revis would have never been hurt... and would still be a Jet. Sparano must have REALLY been a deep-cover Phin spy to sink the Jets, lol.
