I just think too much credit is given to Tebow for winning games. A lot of media (and posters) acknowledge their defense, but it's mostly lip service in favor of cheering for the underdog QB. It's understandable; I often find myself chuckling through what now seems the inevitable comeback.
I used to say that Elway could win most of his games if it was close. The good teams knew this, which is why Denver was blown out in 3 SBs in the 80's. Denver's defense wasn't up to that challenge.
Checkout the teams Tebow, uh, Denver has beaten: Miami (on their losing streak), KC, Oakland, Jets, Bears (minus QB & RB), Chargers, Vikings. All are teams with issues, and only the Jets seem playoff worthy. This week it's NE, who has the offense but questions on defense.
Of all the comebacks, the only one that impressed me at all was the game against the Jets. How can you play shit for 3 quarters and reverse that trend so many times? Only if the other team lets you.
IMO, if the Broncos make the playoffs they seem unlikely to win more than one game.
