Tony Dungy was thinking about retirement after last season but he just couldn’t get the taste out of his mouth about the way last year ended with a 28-24 home loss in the playoffs to the Chargers.  Dungy will have some injury issues to deal with as Peyton Manning and Marvin Harrison are both recovering from major surgeries.  The Colts proved that they can win without Harrison last season but if Manning misses any time this year, Dungy will wish he retired.  Dungy has been great as head coach of the Colts as he is 73-23 (76%) during the regular season the last six years.  He has also compiled a 7-5 record (58.3%) in the post season for the Colts including a Super Bowl Championship in 2006 over the Bears.  Dungy has redeemed himself in Indianapolis after pretty much getting run out of town in Tampa with the Bucs winning the Super Bowl the year after he left under Jon Gruden.  Dungy has now been a NFL head coach for 12 seasons in which he has compiled a 127-65 (66.1%) regular season record and a 9-9 (50%) post season record.  Look for Dungy to lead the Colts to another good season as long as Peyton Manning is healthy.
