For those who don't know, here is my premise:
If Planet Earth were involved in a winner-take-all one-game basketball playoff against an alien invader, the loser to go into servitude for all eternity, my first pick of anyone who has ever played basketball in our known world would be a healthy Bill Walton. He was the most complete center ever, the perfect control tower through which to run both your offense and your defense.
But a career? Well, of course not. Injury prevented him from having the career he deserved. But for one game, I think he's the most important player who has ever laced up a sneaker.
So when I name the all-time centers I put him over on the side.
