NASHVILLE, Tenn. (AP) Predators captain Roman Josi heard about San Jose trading for Erik Karlsson just before talking with reporters at the start of Nashville's training camp.

Yep, the Predators haven't even raised the banner yet for winning the Presidents' Trophy as the NHL's best team in the regular season, and it's already ancient history - at least in the arms' race that is the Western Conference.

Even with all the trades last season and more deals and signings during the offseason, the pace has only quickened as NHL teams prepared to open training camps. First, Vegas added Max Pacioretty from Montreal on Monday, and the Sharks tried to top that by picking up two-time Norris Trophy winner Erik Karlsson from Ottawa.
