Will he start? Won't he start? It doesn't matter. Denver Broncos (backup?) quarterback, underwear salesman and clean-living phenomenon Tim Tebow has sold a lot of No. 15 jerseys since the team drafted him in April 2010; in fact, his jersey has consistently been one of the NFL's top sellers. But jerseys are expensive, which gave Daniella Grieve, of Lombardi's Embroidery in Arvada, an idea: Bring her your old Brandon Marshall (remember him?) No. 15 jersey, and she'll replace the former Broncos wide receiver's name with Tebow's for $25. It's a bargain for Denver fans and a good way to make sure that Tebow groupies keep their shirts on.
