it matters for the rockets because it lets them have a wide ranger of lineup options against teams like the warriors and spurs.
Look at their starting lineup vs the jazz last night. 3 guards in harden, beverly, and gordon along with ariza and capela. Not saying that's what they will run all the time but this can be used against golden state if they put harden on draymond on defense. All they while they have so much outside shooting its ridiculous.
