Football is largely determined by luck. The Colts were lucky to have the number one pick in 1998, and even luckier to endure just one horrible season before having the number one pick in 2012.
Great quarterbacks make everyone around them look better, including coaches.
It is this phenomena that Mike Sando wishes to examine, especially in the shadow of ESPN's current series ranking head coaches in history. The article is an interesting read, and discusses former Colts head coach Tony Dungy and quarterback Peyton Manning.
Dungy: I listed Dungy 20th on my ballot because he won with two completely different types of teams. However, I also think a case can be made that the Colts should have enjoyed greater playoff success during the Peyton Manning years. Ultimately, I point to the success Tampa Bay enjoyed beginning in 1997 with a team built to some degree in Dungy's defensive image. The Buccaneers went 48-32 in their final five seasons under Dungy. That franchise was floundering previously.
