While I believe that the NHL is going in the right direction in dealing with concussions the past few seasons, it must be pointed out that Stevens coming back in that series, and the rest of the 2003 playoffs, basically led to us winning our third Cup. We likely would not have won it without him. While Stevens could have had severe long term effects from his decision to keep playing, at least something good came out of it. Just goes to show you how good, strong, and tough he really was.
Stevens winning the Cup should not have to be pointed out or have a star next to it. The fact is he shouldn't have been playing and perhaps continuing to play ended his career. Now maybe that 3rd Cup to him is worth his career ending short. After all his career ending short was at over 40 when he had already was in the top 10 of games all-time. But was it worth Crosby playing 1 extra game if he never recovers? Would it be worth for Marc Savard if he came back too early 2-3 times. What about Kariya and Lindros? And it certainly might not be worth it for anyone who came back early if their are long-term affects that ruin people's lives after hockey.
I don't think it goes to show "how good, strong, and tough" Scott Stevens was. People have been playing hockey and other physical sports for years minutes, hours, and days after a concussion. It just shows how either dumb we have been, or how little we have known.
