I give it a 99% chance of not happening.
This team only had a chance on a night when everyone was hitting their shots, including IT. Without him, there's no go-to scorer on the roster unless Brown or Rozier makes a major leap. they're really the only 2 players with the moves to get open on their own.
KO had his one explosion this playoff, I don't expect him to come close to that again. He'd need to come close to that level of performance for the C's to have a chance to win a game.
