Sorry, can't agree at all.
I played elite youth sports, tennis was my game, and I know something about performing in big matches.
This 'bottle' that you speak of is what every sportsman known to man lives to find within themselves.
If you aint got none son, then you aren't in the hunt for any big match, any time. In fact, the argument you make about being down on his game at the time serves as a stiffner at those moments. He had everyone pulling for him, most thought he was in the wilderness so expectations were far lessened, and knowing Alex he'd had a drink or two leading up to it. Were this his first visit to the WC it would have been a far more impressive feat in dealing with the situation.
You belie your experience in the game to so dismiss cue ball control as a thing of recent times and modern tables. That's absolute rubbish. From the very beginnings of the game in billiards, cue ball control was and has always been everything. Alex just seemed to play close enough is good enough style control for much of his career, and rely on shot making to cover it up.
He stood up, yes, and it is a historically noteworthy match.
But greatest break ever?
Get over yourself.
