This was kind of interesting to look at as i usually don't look deep into TOI around the league.
For Centers.
A couple that stood out were Travis Zajac averaging over 18 minutes a game
Boone Jenner at around 17.5 a game.
I also really like Chris Tierney in general but he is at around 17 per game. Product of the situation but that is a solid amount.
Also Lars Eller coming in around 17. Yuck.
Based on output though, the answer has to be Brassard or Pavel Zacha.
For wingers, Joel Armia or Darren Helm. Both around 15 min per game.
