Herro, Nunn and Robinson are just rookies/sophomores. They need to bulk up so that they can stand on their own in defense. Offense they have the tools already. These Finals games are very valuable for their exposure and experience. Same thing happened before kila Tatum, Brown etc. when they had a deep playoff run.
In hindsight Kuzma is not living up to the pre season expectation that he will be the third star of the Lakers. I think Vogel should insert a wildcard of a player in Game 6. Its already been 5 games and more or less the defense of Miami knows how they should guard against the likes of Rondo, Caruso, Pope, Green, Kuzma and Morris. Give Dwight Howard more playing time sa 2nd unit. JR Smith can be called upon as well for a few minutes. Just change something sa rotation that will somehow cause imbalance sa defense ng MIA for Game 6.
