After the 2001 season Tony Dungy was fired by the Buccaneers and hired by the Colts. The following season, Jon Gruden lead the Buccaneers franchise to its first ever Super Bowl, something Dungy couldn't do in his entire time in Tampa.
Today, if Jim Caldwell and the Colts are able to beat the Jets in Indianapolis, it would mark the second time that a team in their first post-Dungy year went to the Super Bowl.
To Dungy's defense, he was able to lead the Colts to a victory in Super Bowl XLI, but many people think that a "tougher" head coach could have guided the Colts to Super Bowl victories in 2005 and 2008 as well.
Gruden and Caldwell are much tougher than Dungy. You can tell by the ferocity and focus that the 2002 Bucs and 2009 Colts have played with it that there is something ant-Dungy to them.
Maybe it's just that the Bucs and Colts were ready to become Super Bowl champions and it took the focus of a "new system" to motivate them to that point.
But then again, maybe it has something to do with Dungy be just a little too "soft."
