Probably not. Lillard is a better player but by how much? He can certainly score a ton, but his defense is awful, and frankly I thought Holiday was a very underrated guy for them. Giannis isn't kidding when he says Holiday was a big reason they won in 2021, him and Middleton were huge when Giannis was out in the ECF, and Holiday + Lopez was lowkey clutch for them last year while Giannis was out.
MIL has probably accepted they can't win with defense and will try to outscore opponents now
I'm guessing MIL thought if Holiday was going to go somewhere else, it'd be to Clippers or Sixers. They probably didn't expect Heat or Celtics, and it happened with the Celtics
