You are relying too much on the three and not considering every other variable of the game that equally matters.
Like everyone else has said on here, they would have to shoot much better than they already do at 3 and how are they going to magically do that against the greatest players of all time. Because if they miss, its in the dream teams possession, if the dream team misses, guess what? It’s also in the dream teams hands until they make it. GSW just won’t compete with that kind of level of rebounding, defense and physicality.
You keep thinking how is the dream team going to guard GSW. How in the world is anyone other than maybe KD going to guard anyone on the dream team? Magic, nope. Charles, nope, Karl Malone, nope, David Robinson, nope, Jordan, nope, not even close.
I would also be concerned about GSW fouling out because of the physical dominance of the dream team. The claim of Judy clog the middle won’t work either with great shooters like bird, Jordan, Mullin, Stockton, Malone, etc.
It’s not knock on GSW. It’s one of the top two teams of all time, but it’s just not realistic.
