The Broncos are stuck now. They are stuck with playing Tebow for at least the next 3 games maybe 4 to get through an entire month of play. They made that choice and now they are stuck with it.
The Broncos caved in to fan and media pressure and put Tebow in as their starting QB starting with the Dolphins. He managed to get a win against an abysmal team who played the wrong defensive package to prevent the win. For 55 minutes of that game, he played truly terrible football. The next game versus the Lions, Tebow played almost the entire game badly. His defenders say it was the Broncos play calling that made him play so badly while his detractors say that Tebow further proved his deficiencies on the field in the game. But the Broncos are stuck with it now.
