Longtime coach and former player Bruce Boudreau has connections in some way to every playoff team, some closer than others.
''There's a lot of pride in players that you coached,'' Boudreau said. ''There's very few players that I've coached that I haven't seen and felt a sense of pride or hopefully that you helped them in the tiniest way get to where they were. ... But at the same time you still want to beat them like they were your brother. If you ever play, contested against your brother or your best friend, that's the hardest guy you ever work against, too.''
