Luka offers zero resistance when an opposing guy drives. It's why someone can just roll to the rim uncontested OR if they are contested, someone is open and the "go-to" plan for Boston seems to be Holiday in the dunker spot, or someone for a corner 3. They just attack that.
Idk what Dallas can really do to adjust. I mean, Game 2 was Boston missing a ton of shots. Is that gonna happen a lot this series? I doubt it.
