I don't think Briere will be interested in Rossi.
He likes bigger centers, he seems to be OK with smaller wingers but wants them to have 'true grit,' like a certain player who excelled in the playoffs.
Flyers are one of the smallest teams in the NHL, I don't think Briere wants to get any smaller, and Rossi isn't an elite offensive talent. He's a solid player, but not one you break the bank over.
