If Bill Walton had been as good at basketball as he is at talking...well, actually he was probably better.
As a young player, Bill Walton was as good as any big man and possibly the most fundamentally sound big man of all time. He could do just about anything on the basketball court except stay healthy. His feet basically crumbled and later in life, his spine did too.
But he was there at the very top of the game for a little while and even at the end, after all the injuries, when he had a couple of seasons with the Boston Celtics, the man could still play at a high level.
