Nope, Pop, I would argue and show evidence, that he is far superior to all 3, when it comes to X's and O's and he could get more out of lesser talented players. That's not to say the other 3 coaches aren't great, but seeing them with mediocre rosters.
I agree with the other posters. Doc Rivers isn't a horrible coach but there's no way he should be among the 15 all time greatest while Rick Adelman isn't
2 days ago I thought this was a joke. But now that I’m a 76ers fan I have to say Doc deserves to be there.
