There's a consistent legacy for ya.
It was tough for Chip and in fairness it was written that Chip's choice was actually Leslie Frazier, but he differed to GM Billy Devaney who really wanted Spagnuolo. Chip had to not only sell the team, but also sign off on a new Head Football Coach too and he truly never wanted to be involved in the family business.
Chip also tried to sell the team to a guy in Shad Khan who was commited to keep the team in St. Louis only to be trumped by ESK who at the last minute swooped in to purchase the rest of the team. So again what was Chip's legacy, well, he got rid of the gold pants, signed off on a Head Coach who's record ended up being 10-38 and could not stop the move back to Los Angeles.
Other than that, Chip did one hell of a job.
