Im confused why some here believe a joining of the big 3 means the death of the NBA. If anything it will mean more CASUAL fans watching the NBA. This is why Boston and LA have so many fans nationwide is because they win ALOT. They literally run over teams. You have the haters watching to see them lose. You have the band wagoner's watching to see them win.
Those 3 running over teams would probably send NBA TV ratings sky high. We cant think like a diehard fan. We have to think about the casual fan who wont watch their team lose but they will watch to see Lebron and company. Guranteed stars in the Finals every year is probably a wet dream for David Stern.
Their will be parity between the lower level teams to keep the diehards happy anyway.
