When the Dolphins needed a replacement for general manager Jeff Ireland back in 2014, two of their finalists were Brian Gaine and Dennis Hickey.
Hickey ultimately got the job; Gaine consequently left the organization after six years in Miami.
Now, in a strange twist, Gaine and Hickey are linked together again.
The one-time professional rivals will be colleagues.
The Bills on Friday hired Hickey as a senior college scout, which has always been his strength during a long NFL career. The move came just days after Buffalo named Gaine, who was Ireland's top lieutenant during the last two years of Ireland's tenure with the Dolphins, as vice president of player personnel.
