Embid A) provides Knicks a bonafide inside-outside halfcourt offense to lessen Brunson's (too) high usage, B) sets some nasty good high screens for Brunson, and C) helps better control defensive paint letting perimeter guys release/run a bit more, get some easy buckets.
PHI needs a 'change in scenery' from the Embid groundhog day effect, and KAT still young enough for a retool, essentially now playing in his own back yard, with PG still an above-average team defender.
