Or it could be case of Mays, Mantle, Snider and Ashburn. It may depend on how much one views them in relative terms to each other or in relative terms to everyone else.
How about as the Isaiah to Magic or Bird, or Barkley to Jordan? He's not The Guy. But that guy isn't The Guy without him.
I like the analogy I've made in the past. If Misawa/Kawada/Kobashi are Jordan/Magic/Bird, then Taue is Scottie Pippen-a level below the other three, but still an all-time great in his own right.
