I don't think they can. Simmons is criminally underrated - he's controls the pace of the game and is flanked by shooters. Their defense is elite. And Embiid is a really tough match-up. I think they're ECF-bound.
I predicted Bucks in 6-7, but the Celts have overall played well and I think they've got a very good chance to close this series out on Sat. Jaylen has been awesome, and Tatum showed a lot tonight in the 4th qtr.
