From 1992 to 2000, Christie kicked for Buffalo. With the Bills, he would become one of the game's top kickers. He was a key contributor in the Bills comeback win against the Houston Oilers, in which Buffalo rallied from a 32-point deficit to complete the largest comeback victory in NFL history. Christie kicked a successful onside kick, which he recovered himself, and also kicked the game winning 32-yard field goal in overtime. His kicking shoe from that game is displayed in the Pro Football Hall of Fame in Canton. He then went on to kick five field goals in the Bills 29-10 win over the Miami Dolphins in the AFC championship game, helping Buffalo get to their third consecutive Super Bowl. In 1993, Christie set a Bills record by kicking a 59-yard field goal in a regular season game. It was only four yards short of the all-time NFL record. In Super Bowl XXVIII, Christie set a Super Bowl record by kicking a 54-yard field goal. It is currently the longest field goal ever made in Super Bowl History. In the 2000 season, Christie was an instrumental part of the Bills' eight victories. In week 1 vs. the Tennessee Titans, Christie went 3 for 4 on field goal attempts. The 33-yard field goal came with just :35 to play, giving the Bills a win over the Titans, who had knocked them out of the playoffs the year before. In week 7 vs. the San Diego Chargers, Christie kicked a 29-yard field goal with just :11 seconds to play, forcing the game into overtime. Christie then nailed a 46-yard field goal in overtime, giving the Bills their third victory of the season. In week 9 vs. the New York Jets, Christie went 3 for 4 on field goal attempts. The 34-yard field goal came with just :03 seconds to play, lifting the Bills to 4-4 on the season. In week 10 vs. the New England Patriots, Christie kicked a 48-yard field goal in rainy conditions with just seconds to play, forcing the game into overtime. Christie then nailed a 32-yard field goal in overtime, sending the Bills to 5-4 on the season. Before the 2001 regular season Christie was placed on IR from an offseason injury having accuracy problems during the preseason being replaced by Jake Arians prior to the start of the season. Christie eventually got cut later in the season. Christie has nine field goals in overtime to his credit, an NFL record he shares with Jason Elam and former NFL placekicker Jim Breech.
Later career
From 2001 to 2003 he played for the San Diego Chargers, who, with the hire of former Bills GM John Butler, acquired several former Buffalo players. In 2004, Christie was signed by the Jacksonville Jaguars to put some pressure on struggling rookie Josh Scobee. Christie requested his release from Jacksonville after a week in camp hoping to retire, but signed with the New York Giants a day later, playing what would be his final NFL season. In his 15 NFL seasons, Christie converted 336 of 431 field goals and 468 of 473 extra points, giving him a total of 1,476 points. On July 2, 2007, Christie joined the Toronto Argonauts of the Canadian Football League by signing a practice roster agreement with the team. On the signing, Christie pointed out that one reason for joining the team was "basically doing Michael a favour" as a former college teammate and that it was tentatively for one game. The other reason was that as a Canadian citizen, playing one game in the CFL, would be great way to finish his career. Christie was activated to play on July 7, 2007 against the Hamilton Tiger-Cats. On March 5, 2008 Christie retired from professional football. The Buffalo Bills officially signed Christie to a one-day contract, thus to retire as a Buffalo Bill. He currently resides in Bradenton, Florida, with his wife Kelly, daughter Clare and Chocolate Labrador Retriever, Killarney.
