The Cs are currently on the cutting edge of the NBA newest roster trend playing big small ball and this is going to continue to kill the traditional big man. What I mean by "big small ball" is the ability for teams to play 5 shooters and space the court without having a bunch of under size players at each position. When the Cs start Morris (and down the road Hayward) they are able to play a 6'10 big, 3 6'8-6'9 wings, and one traditional guard. This is the same concept that the Warriors dominate with and why positional size and length are so important.
With a main 15 man roster I would think that the ideal roster construction would be (2) stretch 4/5s, (1) traditional big, (4) guards, and the remaining (
spots going to wing players with at least 2 of them having the strength to defend respectably in the post. I would then use the 2-way on 1 traditional big and a filler prospect.
