Brunson is a better floor general and high-level orchestrator.
Brunson can point to where the entire team has to be to attack a defense or get an open look whereas Kyrie’s assists are more attack a defense/drive and kick variations. Brunson understands the more wholistic/team game and Kyrie the more individualistic one.
Short term playmaking vs long term play making/planning. A point guard in basketball is basically the quarterback of the team on offense. He’s the main facilitator/playmaker who sets the plays for his team.
Kyrie is reactive with tunnel vision and focuses on immediate individual plays( like beating an opposing defender 1 on 1 ) while Brunson is more patient and proactive and has the vision to see the bigger picture on the court. He tries to make all his teammates involved in offensive schemes meanwhile Kyrie trying to play hero ball with volume shooting and trying to win the game by himself.
Brunson is arguably the #1 option on the knicks while Kyrie never been the man in CLE, BOS, Brooklyn, and DAL. Brunson can be the Batman on a team but not Kyrie because he’s a better playmaker, facilitator, leader, floor general than Kyrie. But Kyrie is better defensively than Brunson though.
