He'd simply take Sunny's old spot on the roster... except he'd be a part-time goon who we put out there when we want to wear their d-men down in their own zone along the boards instead of use him on the PK like Sunny.
Right now, it looks like Lapierre is currently on the Habs' 23 man roster.... I think theoretically he'll take that spot and Lappy plays another year on the farm, which is what the organization wants I believe.
For a guy who causes 20 goals a year, I'm surprised he manages to maintain a career +13...
Plus/Minus... the most over-simplified stat of all time. It's the reason Brian Pothier gets $2.5m a year. Giveaways/Takeaways is way better. Actually watching how a d-man handles situations is about 100 times better than any stat.
