There hasn't been a repeat champion in the NBA since Peaceniks did it in 2017, 2018. Not even close. The only teams to make the Finals more than once in the last seven seasons are Peaceniks, Miami, and Beans (twice each). But history...
Oklahoma City is lived history. Show me the weakness on that team. You can't. There is none. I will be smack-me-in-the-forehead-with-a two-by-four gobsmacked if they don't repeat. The only thing that can stop them, it says here, is a season-ending injury to Shai Gilgeous-Alexander--not that SGA is their whole team, far from it--but he is their sine qua non.
