Some of the early considerations would be Eagles offensive coordinator Marty Mornhinweg, whom Grigson knows from his days in the Eagles' personnel office. Another possibility could be Broncos offensive coordinator Mike McCoy, who has become a hot name because of what he did with Tim Tebow and the Broncos' offense. There is an outside chance Grigson could interview Marc Trestman from Montreal of the Canadian Football League.
The key to all of this, though, might be what happens at defensive coordinator. One of the things that could have kept Caldwell as the head coach would have been the hiring of Steve Spagnuolo as the defensive coordinator. A lot of the drop-off on offense came with Peyton Manning sitting out the season with a neck injury. But things were so bad with the defense that Larry Coyer was fired during the season and replaced by linebackers coach Mike Murphy.
