The Blue Jackets formally introduced imports Jeff Carter and James Wisniewski on Thursday. Carter will wear No. 7, while Wisniewski will don No. 21. "Obviously with the acquisition of (Carter), it made my decision easier to come here," Wisniewski said. "As a free agent you want to come to a winning team. You don't want to spend six years of your life losing here." Carter was acquired June 23 from the Flyers for right winger Jakub Voracek and draft picks. "Top centers are not easily available," general manager Scott Howson said. "I think before we acquired Jeff, in the last decade or so, only two had been traded. They were Joe Thornton (of the San Jose Sharks) and Brad Richards (of the New York Rangers). If you look at all the top teams in the NHL, all the true contenders, they're strong down the middle, whether it's Vancouver, Philadelphia, Chicago."
