And the reality is, all of these teams will have that sort of a problem i.e. multiple 25+ scorers on the same team.
Yes and no. I think there are plenty of 25+ ppg guys who shared the ball. A team with Magic or Bird plus another volume scorer isn't going to have the same issue as two guys who were little more than scoring machines.
I agree with Who's point, though. It's probably possible to build a well-rounded team even with two one-dimensional scorers. The rest of the team needs to supply the defense, rebounding, ball-movement, etc., though.
From my perspective, putting five great scorers together doesn't automatically win the "best offensive team" award.
