In the NFL, the running back is a running back.
Running backs are big, mean, and tough.
If a runner runs a flat tire in a game, he will get a flag for holding the ball and get sent to the sideline.
The NFL uses the term “flat tire” to describe a runningback that has a flat spot in his feet.
Some of the worst run blocking run flats in the NFL are: The Rams running back had a flat on his helmet in the first quarter of the 2017 season, the Cleveland Browns running back ran a flat in Week 4 of the 2016 season, and the Jacksonville Jaguars running back was penalized for holding a flat when he broke up a pass against the Philadelphia Eagles.
