Some things never change. He was wearing a different jersey and playing a different position, but Dustin Byfuglien was a Sharks killer once again Saturday night with a third-period power-play goal that proved to be the winner as the Atlanta Thrashers beat San Jose 4-2 at HP Pavilion. Traded to Atlanta from the Chicago Blackhawks and moved from power forward to his original position as a defenseman, Byfuglien had been booed all night by a crowd that remembered the damage he inflicted on the Sharks in the Western Conference finals last spring. But if the Sharks were bothered by the fact it was Byfuglien once again doing the damage, they kept it to themselves. http://www.mercurynews.com/sharks/ci_16360462?source=rss&nclick_check=1
