The NFL has a good amount of running backs that have fast-break speed. Some say the days of a power running back have passed.
Today's prototype NFL running back is a multi-faceted player who can contribute as a runner and pass-catcher, similar to Alvin Kamara of the New Orleans Saints or Christian McCaffrey of the Carolina Panthers. The big power backs are fewer and farther between, and the fullback position has become almost obsolete.
There's still room for power running backs like Derrick Henry of the Tennessee Titans and Leonard Fournette of the Tampa Bay Buccaneers, but they're not the norm like they used to be.
Looking back to the NFL's past, these five running backs were not afraid to lower their shoulders and deliver a hit on anyone.
5. John Riggins
John Riggins played running back for the New York Jets and Washington in the 1970's and 1980's. He is known best for his time with Washington and for his hard-charging running style.
Riggins racked up 11,352 rushing yards in his pro career. He rushed for 104 touchdowns. In the 1980's not many running backs caught the football out of the backfield.
Riggins would tally up 2,090 receiving yards in his career and 12 receiving touchdowns. Riggins won many awards while playing for Washington.
John Riggins would be selected to the NFL Hall of Fame. He made the Pro Bowl and an All-Pro team. Riggins would win a Super Bowl with Washington and be named to the Hall of Fame All-1980's team. Riggins will go down as one of the best running backs to ever play the game.
4. Mike Alstott
Mike Alstott was the power back for the Tampa Bay Buccaneers. Alstott was the last of the power back generation in the NFL. The Buccaneers would use Mike Alstott at the fullback position the majority of the time. As a fullback, Alstott would rack up 5,088 rushing yards.
