Olsen has good size and plays more of a shutdown role. His skating is good enough to contribute to the offense and get a fair share of assists. He isn't going to carry the puck like Campbell, but I think he can get the Panthers 20A this season. He is more of an at home defenseman, but because skating is not a liability he can move the puck adequately. His upside is that he could become a steady #4 defenseman and plays physical.
Olsen is a better than average hitter and has good size. He is not the best fighter. He isn't a horrible fighter either. Expect one to two fights a season where he sticks up for a teammate. You're not going to catch him starting fights. I think he is capable of putting up 30Pts a season next year and building from there. He has a hard shot, but it needs considerable amount of work before he gets power play time.
