"New Indianapolis Colts general manager Ryan Grigson labored all weekend over whether to retain or fire head coach Jim Caldwell.

Because it was a close call to fire Caldwell, Grigson and Colts owner Jim Irsay have to be able to find the right type of coach to rebuild the franchise. More than likely, they will look for an offense-minded head coach.

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."
