Arizona acquired Madsen from the Flyers, who drafted him in 2013, as part of a trade between the teams on June 16.
Madsen won a school-record 28 games for Harvard University as a junior last season. The statistics major will return for his senior season in the fall.
"I think that I found a level of consistency that I didn't have the year before," Madsen said. "Obviously I have to thank my team because they did a lot, but I think I found a level of consistency that I want to improve on even more next year … (Playing for Harvard) has its challenges. When you're at an Ivy League school like that there's a certain level of dedication you have to have with your schoolwork. If anything, it helps me find a balance in my life. There's always something I've got to be doing so it keeps me focused and dialed in."
Madsen honed his hockey skills while growing up in Acton, Calif., about an hour drive northeast of Los Angeles. He stands 6-foot-5.
"I'm a bigger guy, taller guy, so I can use my size a bit more and play back a little, but I also rely on my athleticism and agility to move around quick," Madsen said.
Madsen has enjoyed his experience at the development camp, which included a visit to a local hospital.
"I'm just trying to be a sponge," Madsen said. "I'm just trying to take in everything I can. This is a development camp, obviously impressions are being made, but I want to ask questions, I want to learn something and get something out of the week I have here. It's a short amount of time, but if you ask all the right questions you can get a lot out of it."
