I was curious about where that "Believe" rock in Konstantinov's locker came from so I did some googling and found an LA Times article from '97 that says it was Kozlov's rock.
The day after Kozlov ended a contract dispute and rejoined the team, he placed in the palm of Konstantinov's gloves the lucky rock a fan had sent him last May for his birthday. On the rock is written the word Believe, and that has become the Red Wings' mantra. Each player has on his uniform a patch with the word written in English and Russian and the two injured men's initials, and the motto is not taken lightly.
It'd be pretty cool to be the fan that sent it knowing the part it played in the 98 cup run. To this day I think players touch the rock before games if I'm not mistaken.
