Ginobli, Diaw, Splitter, and Danny Green are just role players. They just won another championship.
This concept that all role players are basically the same, and you can cram any 3 superstars together and any cast of role players, and they will win a championship, is ill-conceived and misguided.
Even the 08 Celtics won as much because of huge contributions from their excellent role players, as they did from the Big 3.
The only reason to give up so much for Wiggins would be if you were pretty sure he was going to be at that MVP level Like Lebron, Kobe, MJ.
