Jim Caldwell.
Before this year (which he is still responsible for at least 2 of them), this man was the sole reason for 8 of our last 10 losses, including losing an undefeated season, losing a Superbowl (yes, the refs screwed us hard, but they don't get that chance if Caldwell doesn't suck) and the Jets game last year. As well as his awful end of game handling of the Jacksonville Jags.
This could be one of the greatest years in Colts history if we run the table in reverse, not just because we would get the next Peyton Manning in Andrew Luck, but because there is no way this moron survives (sadly, only in a work sense, not physical sense) an 0-16 campaign.
A good coach for Peytons last 3 or 4 great years, and then Luck's career, man, that would be amazing.
Will list Hogan reasons soon. Sounds fun.
