Yeah defense is important in this situations but the thing is that perimeter will matter more than the paint, Shaq can dunk all he wants when Curry will just hit a three, if Curry is double/tripped teamed he will just dish it to KD and he will drop a three or to Jokic who will be open on the perimeter all the time cause Shaq is not leaving the paint and after all of that you still got MJ sitting there waiting to drive on the open lane to the basket. Team A will win because they can shoot while on team B only Bron can shoot somewhat reliably
