ARLINGTON, Va. (AP) — Count Washington Capitals defenseman Matt Niskanen among those around the NHL taking a wait-and-see approach when it comes to the league's new 3-on-3 overtime. A few things do seem clear about the setup: It will make goalies' stats uglier, result in fewer shootouts and force coaches to decide whether to focus on defense or an all-out attacking style. "I wasn't really sure about it at first," said Niskanen, whose team hosts the New Jersey Devils in a season-opener Saturday.
