No and they don’t need to
After the All Star break the Knicks had the third best record and they showed in the playoffs that they were significantly better than the Number 4 Cavs. With turmoil from last season carrying over to the Nets and now the Wizards looking like they will tank, the East should have a few more wins available. Knicks had two surges last season; going to the 9 man rotation and then trading for Josh Hart. Both are repeatable. I think RJs improved shooting in the playoffs shouldn't be overlooked either because it was a result of a change in mechanics rather than just luck.
It's kind of weird that you say "one All- Star caliber player (Brunson)." I get that you don't like Randle but he's made two All Star and two All NBA teams. Whatever your personal gripes, he's clearly an All Star calibre player.
