I'm making a point. If you induct a group, everyone associated with that group would be part of the HOF (that includes Benoit).
I don't know how they arrived at the decision, but the only men specifically recognized as Horsemen at the ceremony and officially inducted into the HOF are Blanchard, Arn, Ric, Dillon, and Windham.
Again, I don't understand how and/or why Vince chose those guys specifically, but they are the only men to have received rings and have their names entered on the HOF roster as Horsemen.
Apparently, just "being" a Horseman wasn't enough to qualify. Not saying I agree or disagree with it, but that's how it is.
