Michael Phelps for individual performances over a career, Brady for team sports.
Jordan is of course up there, but the biggest difference is Brady has NO room for error in the playoffs. One loss and they are gone, Bulls just needed to win 4 of 7, they can lose a game or two.
I haven't looked it up, but I know for sure that the Bulls lost the first game in a playoff series in some of the years they won it all. If that were the NFL, they wouldn't have won the Championship or made it through that round.
