ok, hof is based on more than stats and all-star appearances. as you yourself wrote, you need to make an impact on the game. Carter
did not, except as a flash in the pan athlete and the leader of a garbage team, mullin most definitely did. and it won't show up in a stats and all-star based analysis. his team had 3 great players so stats were evened out between them and he had a huge amount of competition at his position so asg apearances were tougher to come by.
ask anyone who watched gstate in those days whether they think he belongs in the hall and every one of them would agree that he does.
i didn't skim through what you wrote, i ignored most of it because you never saw him play and are trying to judge his hof status by a few paragraphs on a message board.
