LaDainian Tomlinson probably doesn't get enough due, historically. He's one of the greatest running backs in NFL history.
He's fifth all time in rushing yards and yards from scrimmage, second all time in rushing touchdowns, and his 2006 MVP season stands as one of the greatest seasons the NFL has ever seen. The San Diego Chargers will honor him as one of their all-time greats, making him the fourth Charger to have his number retired. Tomlinson's No. 21 will go alongside Dan Fouts' No. 14, Lance Alworth's No. 19 and Junior Seau's No. 55.
