As to whether or not those pots will shatter ... Eventually and probably at the worst time possible.
I'm not so sure. I've had pots ping on for days and days after firing, especially when I was salt-glazing, and testing liner glazes. I've never had a single pot shatter (once cooled and out of the kiln).
It seems likely that the pinging is due to crazing - that's normally the case, I believe. This certainly means the pots won't be as strong as they might be, given that the glaze won't be doing so very much in the way of compressing the body. But if they still 'ring' - and OP said they did - then I would rate their chances as better than good.
Something else - OP has fired to 1160 deg C, on a body that claims to fire from 1100 to 1280 deg C. I would guess that 1160 has not fired that clay to proper - optimum - maturity. So again, not so strong. But I still think it won't spontaneously shatter.
And I know nothing at all about hockey, except that when I played at school (not on ice, but on grass), the ball seemed jolly solid, and getting out of the way of it seemed advisable at all times.
