NFL fans know darn well that not even Father Time could stop future Hall-of-Famer Frank Gore from slowing down. As a matter of fact, the oldest active running back in the NFL will indeed return to action in 2019, recently signing with the Buffalo Bills to a one-year deal.

Last season, Gore appeared to be set up for a final run by moving from Indianapolis to his hometown in Miami. The Dolphins witnessed firsthand that the 35-year-old still had plenty of juice left in the tank, playing in 14 games for 156 carries and 722 rushing yards.

However, Miami felt that it was time for the team to move on from the aging back and give its backfield solely unto emerging star Kenyan Drake. But Gore wanted more football, and his decision to move from the sunny confines of Florida to the frigid grounds of Buffalo is a resounding testament to his endurance and passion for the sport.

If there's any doubt that Gore is genuinely dedicated to extend his NFL career further and help out any team that requires his services, this video taken by the Bills' official Twitter account should serve as hard evidence of an all-time great at his finest:

This clip perfectly illustrates Gore's unwavering work ethic. How cool is it for him to don his new team's helmet in street clothes as he struts down the Bills office's hallway with no regard for his image as he's being filmed?

Buffalo is very fortunate to have Gore on its side, that's for certain. And with LeSean McCoy eager to play and learn with a living legend, things are indeed looking up for Bills Mafia.
