Craig was drafted by the Niners in the second round of the 1983 draft, the 49th player chosen overall.
He was named the starting fullback in his rookie year, a position he would have his first four seasons, and showed a nose for the end zone by scoring 12 times. He also led the team with 725 rushing yards.
Craig scored 10 times the next year, and the 49ers would go on to win Super Bowl XIX. Craig scored three times in that game, the first player to have ever accomplished that feat.
He had the best year of his career in 1985, becoming the first player to ever gain 1,000 yards in both rushing and receiving. Marshall Faulk is the only other player who has done this since.
Craig also became the first running back in NFL history to lead the league in receiving, when he caught 92 balls. He also scored a career-high 15 touchdowns and averaged a career best 4.9 yards per carry.
He was named to his first Pro Bowl that season. After catching 81 passes, running for 830 yards and scoring seven times the next year, the 49ers moved Craig to halfback in 1987.
He responded by being named to the Pro Bowl. This is a feat he would attain the next two years as well, becoming the first player to ever go to a Pro Bowl as a fullback and halfback. Only Stephen Davis has duplicated by this since.
His 1988 season saw him rush for a career-high 1,502 yards, catching 76 passes and scoring 10 times. Craig was named the Newspaper Enterprise Association NFL MVP, the Associated Press NFL Offensive Player Of The Year, the UPI NFC Player Of The Year and First Team All-Pro that year.
San Francisco would end the season by winning Super Bowl XXIII.
Craig ran for over a thousand yards for the final time of his career in 1989, getting 1,054 yards. The 49ers won the Super Bowl a second straight season, and Craig scored a touchdown in the game.
He was injured in 1990 and missed five games. The 49ers were trying to get back to a third straight Super Bowl and were beating the New York Giants by a point as time was running out in the fourth quarter. Craig fumbled, and the Giants recovered. New York soon kicked a game winning field goal as time expired.
It was his last play as a 49er, as they would release him. He signed with the Oakland Raiders for the 1991 season. After starting in 13 games, and scoring once on 590 rushing yards, the Raiders cut him.
He signed with the Minnesota Vikings and played two years with them as a backup, starting three times total. He scored six touchdowns over that time and retired at the conclusion of the 1993 season.
Craig's 1,686 carries is the most in team history, 19 more than Hall Of Famer Joe "Jet" Perry. His 7,064 rushing yards is the second most, 1,525 yards behind Perry, and his 50 rushing touchdowns are the second most, 18 behind Perry.
His 508 receptions are the most by any RB in Niners history, and the third most overall in team history.
Roger Craig may be a borderline Hall Of Fame candidate to some, but he is one of the finest players to have ever worn a 49ers jersey.
