Honestly, it doesnt matter to me either way.
BUT I can see where people would. Barry Bonds's ball went for huge money yeah? Bats, sticks, pucks, balls, pads, uniforms, etc all carry some amount of worth in dollars.
Why do people spend big money for game-played sticks? It is just a piece of "wood" touched buy a professional athlete.
In ref to Pronger, those pucks would not have any worth. Nobody would get big ducats for selling the puck that was on the ice at the end of Game 1 or 2.
But the puck that ended a 49 year drought? It would had significant value. And therefore if Miller took it, that could be looked at as a theft. (I am no lawyer so not trying to spark anything there).
The fact that the NHL suspended him for investigation shows there must be SOMETHING to it, otherwise the NHl would have bigger issues I would imagine for pulling him.
