Auerbach as the greatest basketball coach of all times?
You have to be fuc*ing kidding me. That's like saying you would take Bill Rusell (6'9.5'' at CENTER) over Michael Jordan in your lineup for a modern game if for some reason you were able to get both players at their prime.
Hell, I'd take Shack ('00), Duncan('03), Garnett ('04), Hakeem ('94) over any "version" of Russell you want to put on the floor. All 7 footers that would just crush him on the low block.
Sure, they won a lot of championships. You have to take into account that the league consisted of 8(?) teams, there was NO FREE AGENCY so they kept the core players at all times. Also, his team out$pent all others. If it was that easy now don't you think Portland, NY, and Dallas would have purchased championships by now?
