Gustavsson has spent the past two seasons backing up Jimmy Howard in Detroit. He was 16-5-4 in 2013-14 with a 2.63 goals-against average and a save percentage of .907. He was 0-2 with a 2.71 GAA and a .917 save percentage against the Boston Bruins in the Stanley Cup Playoffs.
The 29-year-old Swede has a 57-52-20 career record in 141 games for the Red Wings and Toronto Maple Leafs. He was eligible to become an unrestricted free agent on July 1.
Obviously there's a lot of expectations around me but it's something I try not to focus on. I'm just trying to go out there, be myself on the ice every day, try to get better, be myself around the guys in the locker room. I think that's what's made me successful and the person that I am.
