I personally think Walter Payton was. He played on some really crappy teams. He always seemed like he was at a different level.
So many one dimensional players are lauded as GOAT.
Bob Waterfield was the best all around player. He played both sides of the ball, was a great QB, he was a punter and a place kicker. He played 18 years back when the QB went unprotected and equipment was nothing like it is today.
https://en.wikipedia.org/wiki/Bob_WaterfieldGale Sayers was pretty good in that regard, if we're talking about different level.
I go back, again, to Butkus.
They both played special teams early on. Butkus was literally leveling people and Sayers was setting special teams records.
