Minor quibble: He was fired in Indy because of his awful run of drafts, starting in 2005 and featuring several draft classes completely washed out of the league within three seasons. He may have also been a dick, and unable to get along with people, but had he hit on any number of players in 2010 who've gone on to be superstars instead of taking Jerry Hughes (who was a "bust" in Indy and has resurrected himself in Buffalo), Polian might still be the Colts GM.
2010 draftees taken after Jerry Hughes: Rob Gronkowski, Jimmy Graham, Geno Atkins, NaVorro Bowman, Kam Chancellor, Antonio Brown, TJ Ward, Greg Hardy, Emmanuel Sanders, Alteraun Verner.
