team's third consecutive head coach to win his first game, and the first in team history to win his first game against the rival Cleveland Browns. In contrast to Bill Cowher, who retained only longtime running backs coach Dick Hoak from Chuck Noll's staff (Hoak himself retired just before Cowher's resignation), Tomlin did retain many of Cowher's assistants, most notably defensive coordinator Dick LeBeau, whose defensive philosophy contrasted with Tomlin's. This was done in order to keep team chemistry with the players, since the team was only one year removed from a Super Bowl win at the time of Tomlin's hiring. The Steelers finished Tomlin's first season as head coach with the top-ranked defense in the NFL. Tomlin led the Steelers to the 2007 AFC North Division championship and a 10–6 record in his first year as head coach. The Steelers lost in the first round of the playoffs to the Jacksonville Jaguars, 31–29. Tomlin began his career with a 15–7 record in regular season play—as did his predecessor Cowher and all-time win-leader Don Shula. Tomlin set a Steelers record for most wins, after winning 22 games in his first two seasons as head coach; in addition he became the first Steelers coach to win division titles in his first two seasons. When the Steelers defeated the Baltimore Ravens in the 2008 AFC Championship Game, Mike Tomlin became the youngest NFL head coach to lead his team to a Super Bowl. He also became the third African-American to coach a team to the Super Bowl, following Chicago's Lovie Smith and Indianapolis's Tony Dungy, the two opposing coaches in Super Bowl XLI. After two seasons, with a record of 22–10, he was the winningest head coach in Steelers history based on win percentage (68.8%). On January 29, 2009, Tomlin was named the 2008 Motorola NFL Coach of the Year. On February 1, 2009, at age 36, Tomlin became the youngest head coach to win the Super Bowl when the Steelers defeated the Arizona Cardinals in Super Bowl XLIII. The previous record was held by Jon Gruden, who was 39 when he won Super Bowl XXXVII with the Tampa Bay Buccaneers. Coincidentally, Tomlin was the defensive backs coach under Gruden when the Buccaneers won the Super Bowl and was a key component in their success that year. Tomlin's record was eclipsed by Sean McVay who was 303 days younger when winning Super
