Who cares who would beat who in a game of 1-on-1? Ugh, I hate this mentality.
Basketball is not reducible to who can go 1-on-1, 2, 3, 4 or 5 better than another. People should just disband every team then and just throw everyone into the AND1 circuit and play "seasons" in which everyone can go 1-on-1 and then see who comes out on top at the end of it. Since that's all most people seem to care about.
