Broncos quarterback Jake Plummer has been off target and inconsistent the past two games, throwing four interceptions and only two touchdowns passes.With fans and the media again clamoring for rookie quarterback Jay Cutler, is Plummer feeling the heat?A report on the NFL Network said Cutler will likely start in the team's game against Seattle Dec. 3.However, it will probably depend on how Plummer plays at Thursday's game against the Chiefs in Kansas City.Plummer's record with the Broncos is 40-17, but Broncos coach Mike Shanahan can't afford to throw away the season on a quarterback gone bad."I mean I don't really know what the fans really expect," said Broncos linebacker Keith Burns. "I mean, other than a win, I don't know what they expect. It's not like Jake is going to come over and watch their kids, so give him a break. At the same time, all he does is win, you know, and that's all you want him to do. Regardless of how he plays, if he walks off the field and we won the game, then he's done his job."But with the upsetting loss against San Diego on Sunday, Cutler may soon get his chance as starter.Plummer completed just 13 of 28 passes in Sunday's 35-27 home loss, knocking the Broncos out of the AFC West lead.
