The talk about Tony Dungy stepping down is getting hotter, and now Profootballtalk.com is reporting that indeed, Dungy will announce his stepping down on Monday. The site is quoting a league source as saying that with Dungy stepping down, Jim Caldwell will be taking his place. Caldwell has already gotten interviews with some other teams around the league, and is held in high regard in the Colts locker room. We reported yesterday that it was a done deal that Dungy would be stepping down, and now it looks closer than ever.
