Mud, I'm not so sure about that. The CFL requires a lot of passing and a lot of scoring. Tebow's strengths have always been low-scoring, gritty, squeak-by-the-opponent-right-when-it-matters affairs.
Ideally, if the UFL were still around (and, well, thanks to the Democrats in charge of that league, they ran it into the ground by overspending), Tebow would have been an ideal candidate for them. The UFL or any other lower league would thrive on the publicity a Tebow signing would bring.
