Philadelphia look like a cluster who know what..reminds me of Brooklyn team with Kyrie, Durant & Harden
That first Brooklyn team was good enough to win a title but things definitely deteriorated after that. They lacked the long, athletic, physical support guys who defend, grab loose balls, fight around screens, etc. In short they were slow.
This Philly team looks similar in that regard. I know they haven't technically given up a ton of points, but they do have a lot of old, slow, undersized, or unathletic guys.
Oubre doesn't defend. Yabusele has physical limitations. Maxey is short. Lowry is short and very old. George is old and worn down by years of injuries. Gordon is old. Drummond is lumbering.
Martin is solid and I don't know enough about McCain to comment aside from the fact that he's only 6-3.
And Embiid has visibly declined. He doesn't move great nowadays. At least not consistently.
The Sixers are on BIG trouble. They're a lot like the bucks, actually, but at least Dame is usually available and is pretty clutch with his outside shots.
