6. Rich Gannon
Gannon only lasted four seasons with the Chiefs, much to the ire of fans. Kansas City acquired Gannon as a free agent before the 1995 season, and he lasted through the 1998 campaign before moving onto the Oakland Raiders. There, Gannon would go to a Super Bowl and become the MVP of the league.
Gannon should have been the man to take over for Montana. Steve Bono was insterad given the keys and was terrible. Bono would even get benched in the playoffs for Gannon, who almost led the Chiefs back against the Colts. Somehow, Gannon was left on the bench throughout the 1996 season and the first half of the 1997 campaign before Elvis Grbac broke his collarbone.
Gannon would go 7-0 down the stretch before being benched for Grbac prior to the AFC Divisional playoffs against the Broncos. The Chiefs would go on to score 10 points and lose, 14-10. Gannon was a major part of that 1997 squad, going 13-3 and earning the No. 1 seed for the last time to date.
Frankly, Gannon could be much higher on this list had he been given the chance by Schottenheimer.
