Dan -
I'm a Toronto kid who so loved Bobby Orr that I refused to wear #4 -- even though I was a defenceman and the coach offered it to me -- because I didn't feel I could do it justice, and didn't want to besmirch in any way Bobby's name. [I suppose I was an overly serious 12 year old. I'd read his book, "Orr on Ice", six times, and I was still drinking tons of milk, just like he said he did, along with his steak, as his game-day meal.] And, while it's impossible to take a single thing away from the Great One, truly, from where I sat there was no one, nobody, no one ever, who could control a game and the pace of a game, and make it his own, both on defence and offence, like Bobby Orr. On one knee.
Despite what I said before about none of us knowing anything, I feel safe in saying that Bobby Orr was the GOAT.
Oh, and Ira: on basketball I'm much less sure, and I don't proclaim a GOAT. Jordan was magnificent, but if I were starting a basketball team today, and I had to pick one player to be its centrepiece, I wouldn't pick Jordan or LeBron. It would be Magic.
