Michael Rupp is already familiar with Wild head coach Mike Yeo.
Minnesota acquired Rupp from the New York Rangers on Monday, but back when Rupp was a member of the Pittsburgh Penguins, Yeo was serving as an assistant coach. The two worked on the same team in 2009-10 and Rupp netted a career-high 13 goals. "Playing under Dan Bylsma and Mike Yeo, you were just excited to come to practice every day," Rupp said. "I know that's just how [Yeo] is and how he coaches, and I would expect it's the same thing here. I'm just looking forward to battling for Mike and my new teammates."

The New York Rangers have traded Michael Rupp to the Minnesota Wild in exchange for Darroll Powe and Nick Palmieri.
This isn't a trade that will impact many fantasy teams. Rupp is the most valuable of the three because he at least spends an ample amount of time in the sin bin, but even then it's not enough to counteract his minimal offensive output.
