Tebow’s future hinges on starting

At Dove Valley, one of the gaggle of new radio show gabbers, apparently fresh from his turn with a pail and a shovel for Ringling Bros., provided us with this assay: “The Broncos will win eight games and won’t get to the playoffs. No way Tebow is the starter, but he will be quarterback on third-and-short, fourth-and-1 and close to the end zone.”

Alas, that contradictory contention is widely shared.
If one truly believes that the Broncos won’t reach the postseason in 2010, what would be the purpose of starting a lame-duck quarterback?
