Hatcher was considered a top defensive defenceman long before the clutching and grabbing really became prevalent in 1993-94. He was a highly sought after (and untouchable) defenceman from about 1991 on.
He was never the same defenceman after suffering a torn ACL in October of 2003. During the 2002-03 season, he was a second team all-star and a Norris finalist. It was the peak for a defenceman who, along with Scotty Stevens and Adam Foote, was considered the best combination of physical play and overall defensive play among the NHL's defencemen. He signed the lucrative contract with Detroit, but suffered a torn ACL very early in the year versus Vancouver. He looked lost in the 2004 playoffs against Nashville and Calgary - two of the quickest teams in the league at that time.
At his peak, he was dominant. He was a blueprint for rock-solid defensive defencemen. And he was a great leader. You can't overrate leadership. Ask Pat Quinn about the importance in leadership with Team Canada at the Olympics. The 2002 team had it in spades. It's a big reason they won - Yzerman, Lemieux, Sakic, MacInnis, Nieuwendyk, Peca, Shanahan. We should have seen the red flags go up on the 2006 team the moment Gagne was named an alternate.
