I hadn't really heard about this until now, but then again I haven't really looked at bowling at all except for the past month. I don't hold favor with any bowler, but it definitely seems intentional. I used to buy the flimsy cheapo water bottles all the time and the only time it has ever crinkled is when you're first initially opening it and have to break the seal. After that it's very easy to twist the cap off without applying any pressure whatsoever to the bottle. I find it hard to believe that if you're consciously trying to be quiet, which you would be during a pro game, that you would crinkle the bottle especially at such crucial moments like those.
