Some of you have misunderstood my hypothetical.
It's not the Celtics vs. the Magic. It's Payton, Oladipo, Harris, Gordon, and Vucevic vs. Smart, Bradley, Crowder, Sullinger, and Olynyk.
Pretend they met up in an empty gym somewhere and just decided to play. Make it a seven game series, playground rules, each game to twenty-one, win by two. Call your own fouls.
I'm going with the Celtics.
