Philly vs Clippers would be interesting. The Clippers have no answer for Embiid. But Kawhi and George can both shut down Simmons.
Very few teams have answer for Embiid though but I feel like someone like Harrell, despite not being great defensively, could get under his skin. Beverley lacks size of course, being a point guard, but he could annoy the hell out of Embiid too. The thing about Embiid is that he gets overexcited fairly easily and his game can go down the drain when he does. It's also hard to see Clippers having the ammo to go after a proper rim protector, they could do some digging in the bargain bin and buyout players but they can't really go after Adams, Drummond etc.
I think playoffs this year could be amazing if most star players are healthy, there's so many matchups that could potentially go to 6-7 games. Even in the East where it seemed like it was top 2 and then everyone else it seems like Miami could be a handful for whoever they play. They do strike me as a team that does better in regular season than they are going to do in the playoffs though, as in playoffs what matters more is your top players quality rather than depth as rotations get shortened to 7-8 players.
