Depends if they need to be the 2 best players, because I mean Durant and Klay did pretty well, though obviously Klay was the 3rd or 4th best player on those teams (still all star caliber though). Same would apply to the 80's Sixers with Dr. J and Toney though Moses was obviously their best player. DJ and Gus were the leading scorers on the Sonics, though Sikma was better than Gus. Bradley and Monroe were both top 4 players on the Knicks.
The only 2 champions where the 2 best players were a SG and SF were the MJ/Pip Bulls and the Lebron/Wade Heat.
