Listing Kyle Orton as a potential MVP candidate once would have seemed about as plausible as the Broncos opening 5-0 with victories over the Cowboys and Patriots.

Orton makes his MVP Watch debut -- at the expense of Tom Brady, no less -- because we're far enough into the season for results to matter more than reputations.

The Bears castoff has seven touchdown passes, one interception and that 5-0 starting record. His predecessor, fellow MVP Watch member Jay Cutler, was 17-20 as the Broncos' starter, never winning more than half of his starts in a season. Orton has now won 26 of 38 regular-season starts for a career winning percentage (.684) exceeding not only Cutler's but also John Elway's (.644).

To make Orton comfortable, MVP Watch welcomes fellow 2005 Bears draft class alum Cedric Benson, the NFL's leading rusher for a 4-1 team, to the list. There wasn't room for Mark Bradley, chosen by the Bears between selections of Orton and Benson, although the Kansas City receiver does have as many touchdown receptions as Randy Moss this season.
