Indeed, the revival of the Blackhawks was seismic. Although still in his mid-20s, Keith soon stood as a tenured leader beside such prodigies as Jonathan Toews and Patrick Kane. Keith and his customary partner, Brent Seabrook, emerged as one of the league's most effective and durable tandems. Keith in particular thrived under coach Joel Quenneville, who took over early in the 2008-09 season and espoused an upbeat, puck-possession style. Keith finished the season with 44 points and a plus-33 rating.
The Blackhawks were poised to take the next step. It has been posited that had Keith been a mailman, he's the one who would have taken a walk on his day off. When he's on the treadmill, it's the treadmill that wears out first; on the grueling VO2 max test, Keith scores off the charts. But besides his superior conditioning, there is passion and grit.
In Game 4 of the 2010 Western Conference Final, a puck careened off the stick of San Jose Sharks forward Patrick Marleau. Keith took the brunt of the blow in the mouth, losing seven teeth -- three on the top, four on the bottom. He adjourned for repairs and returned to play 12 minutes in the third period and a game-high 29:02. He blocked five shots, and the Blackhawks swept the series and went on to win the Cup for the first time since 1961. Keith capped his season by becoming the fourth Blackhawks player to win the Norris as the League's best defenseman (Pierre Pilote 1963-65; Doug Wilson 1982; Chris Chelios 1993, '96). Keith won the Norris Trophy for the second time in 2014.
Keith starred on all three of his championship teams with the Blackhawks, but his performance throughout the 23-game postseason run in 2015 stood apart. He averaged 31:07 of ice time per game during a two-month marathon that included five overtime games. One of them -- Game 2 of the Western Conference Final against the Anaheim Ducks, a 3-2 Chicago victory -- became the longest in franchise history at 116:12, of which Keith played 49:51.
