John and Jim Harbaugh will be the first siblings to coach against one another in a Super Bowl this Sunday. Besides knowing which Harbaugh is which (John coaches the Ravens and Jim coaches the 49ers), here are three things to know about John and Jim Harbaugh:
1. Big Brother: John is older than Jim by 15 months, but Jim is taller than John.
2. Success All Around: This is only Jim's second year as an NFL head coach. He took the 49ers to the NFC Championship last season but lost. This is John's sixth season as head coach (all with the Ravens). He has taken the Ravens to the playoffs in every season he's coached, including two trips to the AFC Championship. This the first trip to the Super Bowl for both coaches.
3. Jim's Ravens Connection: The first sack of Ray Lewis' career came in 1996 when he got Jim Harbaugh, who was the QB for the Colts at the time. Also, Jim was the QB for the Ravens for one season in 1998. He threw for 1,839 yards with 12 TDs and 11 interceptions.
