Kelly replaces Jim Tomsula, who was fired after going 5-11 in his only season with the 49ers. That followed four seasons under Jim Harbaugh, who guided San Francisco to a 44-19-1 record, one trip to the Super Bowl and three appearances in the NFC championship game.
Kelly joined Philadelphia in 2013 after four seasons as the head coach at Oregon. Kelly compiled a 46-7 record with the Ducks. Oregon lost to Auburn 22-19 in the BCS national championship game for the 2010 season.
The Eagles went 10-6 in Kelly's first season and lost in the first round of the NFC playoffs to the New Orleans Saints. Philadelphia repeated its 10-6 record in 2014, but missed the postseason. This season, the Eagles had a 6-9 record under Kelly.
Kelly became the Eagles' head of football operations in January, and the offseason was punctuated by the trade of running back LeSean McCoy, the franchise's all-time leading rusher, to the Buffalo Bills, a quarterback swap with the St. Louis Rams, the loss of top receiver Jeremy Maclin to the Kansas City Chiefs via free agency and the signing of running back DeMarco Murray, the NFL's leading rusher in 2014, away from the Dallas Cowboys in free agency.
