Bob Probert might have been the most feared NHL player who ever raised a fist, a wild brawler who often skated off bloodied and battered but to enthusiastic applause. He spent 16 seasons as an enforcer for the Chicago Blackhawks and Detroit Red Wings, avenging slights against teammates and energizing his team.

Decades of fighting on the ice and hard living away from it took a heavy toll though: He died of a heart attack last summer at 45. Probert's contribution as a player was measured in penalty minutes, not in goals. But his posthumous contribution could redeem him — and lead to changes in the way the NHL governs itself.
