I guess they could/should be in the Hockey Hall of Fame. Don Cherry is mostly known for Coaches Corner and Barry Melrose for getting the Kings to the 1993 Stanley Cup Finals.
I guess they would get in under Builders with Cherry being the most likely of the two with his broadcasting career.
I'm finding it hard to put these two in the Hockey Hall of Fame. Alexander Mogilny should be in the Hockey Hall of Fame before these two.
Outside McKenna on Medicine Hat:
Ryder Ritchie Unsigned Wild pick
Liam and Markus Ruck big drop in points after Liam on the team
Shaeffer Gordon-Carroll
Borges at Arizona State is kind of one
MacMillan
To piggyback on this, if you have competent leadership in the coaching staff, you don't really need a "GM" role the assistants can take care of the job
