Question: Who scored more goals over his NHL career, Ballard or one of the two players, Grabner and Bernier , he was traded for? Passage:On June 25, 2010, during the 2010 NHL Entry Draft, Ballard was traded to the Vancouver Canucks (along with Victor Oreskovich) in exchange for Michael Grabner, Steve Bernier and Vancouver's first-round pick, the 25th overall selection ultimately used to select Quinton Howden. After spending two months of the off-season on crutches while recovering from surgery, he reported to the Canucks' training camp, but struggled in the pre-season. Four games into the regular season, he suffered a concussion after being hit into the boards by Los Angeles Kings forward Brad Richardson on October 16, 2010. He was subsequently sidelined for five games. However, upon returning to the lineup, his play continued to struggle. Averaging 13 minutes of ice time a game, he was eventually taken out of the lineup for four games in November by Canucks head coach Alain Vigneault. It marked the first time in his career he was a healthy scratch. After being re-insterted into the lineup, he scored his first goal as a Canuck in a 61 win against the San Jose Sharks on November 26. Several months later, Ballard suffered a sprained medial collateral ligament (MCL) in his right knee during a game against the Ottawa Senators on February 7, 2011. The injury resulted from opposing forward Milan Michalek tripping him from behind, which Canucks general manager Mike Gillis pointed out did not occur anywhere near the puck, alluding to the play as illegal and disrespectable. Ballard finished his first regular season with career lows in games played (65), goals (2), assists (5), points (7) and average ice time per game (15 minutes and 14 seconds). His individual struggles came amidst a franchise record season for the Canucks, who won the Presidents' Trophy as the NHL's regular season champion for the first time in team history. Entering the playoffs as the first seed in the West, the Canucks advanced past the Chicago Blackhawks, Nashville Predators and San Jose Sharks to qualify for the 2011 Stanley Cup Finals. Facing the Boston Bruins, Vancouver lost the Stanley Cup in Game 7. Over the team's 25 playoff games, Ballard dressed for 10. Playing only one game of the final two rounds, he dropped in the depth chart behind Aaron Rome and rookie Chris Tanev.

Output:
On June 25, 2010, during the 2010 NHL Entry Draft, Ballard was traded to the Vancouver Canucks (along with Victor Oreskovich) in exchange for Michael Grabner, Steve Bernier and Vancouver's first-round pick, the 25th overall selection ultimately used to select Quinton Howden
