Bob Cousy won championships in a prehistoric league that had like 8 teams and didn't play basketball at all like it's played today

. His teams also had like 4+ hall of famers on all of them. Do you really think Bob Cousy was any better than CP3 or Deron Williams and do you really think he'd be capable of leading a team to a championship in today's NBA?
Regardless, just for the sake of argument, what year was Cousy the best player on one of Boston's le teams? I can't wait to hear this.
Regarding Frazier, I'll give you 1973, but lets not forget how stacked it was. DeBusschere, Monroe, Bradley, Reed (old though), etc. That team was more loaded than any salary cap era team ever will be.
