Rick Nash was surrounded when he stood in front of his new stall in the home dressing room at TD Garden. While he talked to the media about his first home game and first goal as a member of the Boston Bruins, another player stood off to the side, largely ignored. But the other R. Nash -- that, of course, would be Riley Nash -- could play nearly as big a role in the Bruins' run down the stretch as Rick Nash. The under-the-radar forward has spent this season playing up and down the lineup. He has spent most of his time centering the third line and now finds himself up the depth chart. With top-line center Patrice Bergeron out for at least two weeks because of a fractured right foot, Riley Nash got the first crack at replacing the irreplaceable when he skated between Brad Marchand and David Pastrnak in a 4-3 overtime win against the Carolina Hurricanes on Tuesday. "It's not the easiest of jobs," Nash, 28, said. "I think [Bergeron is] honestly one of the top centermen in the League and he just makes things look so much easier out there. He's always in the right spot, always making the right play. For me, we're kind of in different positions, so I'm not trying to make as many plays -- it sounds bad -- but trying not to mess up." The good news for the Bruins is that, in a way, they have a player in the mode of Bergeron to replace him. As Nash himself would admit, he is not Bergeron. But he has the ability to be a solid defensive center who occasionally can chip in on offense, enough that Marchand referred to him as a "mini-Bergy" after the morning skate.
