There are many in the NBA - Dominique Wilkins isn't in, there are others that escape me.
Ken Stabler, Ray Guy, cliff Branch, Tom Flores, Art Monk not being in. Lynn Swann being in.
Admittedly biased on the Raiders, but Flores is the only coach with 2 SB wins not in (the same holds for Plunkett at QB) and Guy was arguably the best punter ever.
