You love watching RGIII, Colin Kaepernick, and Michael Vick play because they are just as exciting with their feet as with their arms.

Before these guys, however, there was Rockin' Randall Cunningham. Cunningham played QB like no one else before him, running and throwing with gusto.

In 1990 Cunningham finished in the top 10 in the league in rushing with 942 yards. Think about that: as a QB only 9 running backs rushed for more yards!

In 1998 he was named the MVP of the league after throwing 35 TD's and 3,405 passing yards, while leading the Minnesota Vikings to a 15-1 record. Yeah, he was really good!

His combination of size, speed and strength led to a Sports Illustrated cover as the game's "ultimate weapon."

It's not hard to see how Cunningham's dual abilities served as a prototype for the mobile quarter backs so popular among NFL teams these days.

Who is the best running QB in NFL history.
