‘According to Mike Kaminska, the club’s director of merchandise, the run on Eichel items has been “just crazy.’’ Normally, he said, he might stock 144 sweaters ($180 each) and name-and-number T-shirts ($32) for any other Sabres player, and that would be enough for a full season. But the store already has sold 2,000 each of just those two Eichel items.’
