These were among the notable players moved before the NHL trade deadline Wednesday.
Columbus completed three deals, including one acquiring Gaborik from the New York Rangers for three players. Columbus (15-14-7) sits 11th in a tightly packed race for the Western Conference's eighth and final playoff spot.
Buffalo completed its fourth trade in three weeks by trading Pominville to Minnesota in exchange for goalie Matt Hackett and forward Johan Larsson.
Conacher, second in the NHL rookie scoring race, was traded by Tampa Bay to Ottawa for goalie Ben Bishop.
The groove of being behind a bench is going to be interesting at first, but thank God we have a few exhibition games to get rid of those cobwebs. Overall the excitement of it all and the freshness and coming back refreshed, all those things are going to be assets. If [the players] come ready to give their best effort in practice and games, good things are going to happen. I'm always looking for results. It's not always on the scoreboard. It's winning and building something.
