The chant didn’t last long, but its target was clear. With a few minutes to go in the third period of the Bruins’ 4-2 victory over the Islanders Friday night, the fans tried out an appreciation for Dougie Hamilton, the callow Bruins defenseman who appears ticketed for a long tenure in Boston.

That “Dougie! Dougie!” cheer was followed, not long after, by another ode to the player who tallied the first multi-point game of his young career. “Teach me how to Dougie” came on the sound system while Hamilton was on the ice, a song he has gotten used to hearing over the past couple of years.
