6. Mike Hampton

Year: 2001
Contract: $121 million/Eight years
Team: Colorado Rockies
When the Rockies gave Mike Hampton the largest contract in sports history at the time, they figured they would be getting the same dominant groundball pitcher who had gone 22-4 with a 2.90 ERA in 1999. However, once Hampton got to Coors Field he went 21-28 with a 5.75 ERA over two seasons before being dealt to the Braves. Pretty shitty for the same dude who said he chose to go to Colorado "for the school system." FOH, Mike.
