While no one has heard from Colts current coach Tony Dungy for the past few days, there are more indications that he might be ready to hang it up as coach of the Colts. The team has signed current assistant head coach Jim Caldwell to a multiyear extension that will pay him about $2.5 million this upcoming season – head coaching money. The team would pay about $7.5 mil between both Dungy and Caldwell if they are both on the staff, leading one to believe the team is starting to think that Dungy will NOT be coming back in 2008.
