Here in Denver, the "Cutler to start Sunday" rumors are a weekly occurrence. Cutler would have started this season if it weren't for Brian Griese. Why? Glad you asked . . .
Back in 1999, Shanny decided to start the year with Griese at QB instead of locker-room favorite Bubby Brister. At the time, Griese had zero NFL experience and the prior season Brister had filled in admirably for a four game stretch while Elway nursed an injury. It looked to be Brister's job for the '99 season. But Shanny did the old Shannahan Switcheroo and Griese started the '99 season. The team revolted, started 0-4 and quit on Shanny. Mike vowed to never make the same mistake again. So faced with basically the same decision this season, Shanny goes with the proven veteran over the rookie.
Now Jake has had a crap year, that's for sure. But it's not entirely his fault. The Broncos running game is more to blame. There isn't a team in the NFL that fears the Broncos running game. So no teams are worried about the play-action or bootleg -- Jake's bread and butter. Couple that with the fact that Shanny doesn't trust Jake to make a play, the play-calling reflects that, and it is killing Plummer this year.
