I have been involved in many a discussion about the role of the enforcer in modern hockey. I usually fall on the "they have a role" side while others argue that teams don't need them. That is a quite simplified version of the hot air passed back and forth.
That said, let's look at the four teams currently fighting for the Finals:
Boston- Shawn Thorton (3 goals, 60 pims)
Chicago- Brandon Bollig (0 goals, 51 pims)
Penguins- Tanner Glass (1 goal, 62 pims) and Derek Englland (0 goals, 54 pims)
These are all regular season stats. So it does seem that a successful team can have an "enforcer" on the team who fits a role. I didn't include Orr, Neil, Prust, McLaren, Clowe, etc. on this list either. Just my two pennies.
