Stu Grimson's new autobiography is aptly called The Grim Reaper, but the book's subtitle – The life and career of a reluctant warrior – rounds out the picture of the infamous NHL enforcer.

Grimson was a serious handful, a heavyweight who knew exactly how to flatten a foe in as few punches as necessary. But he is conflicted about that role - and much more proud of his leadership in the locker room and on the bench.

The fact that Grimson liked using his noggin more than his knuckles became obvious once he got his law degree and started negotiating in NHL labour disputes.

Host Anastasia Bucsis gets the NHL veteran talking about the main preoccupations of a heavyweight during the height of the enforcer years.
