Tennessee Titans quarterback Marcus Mariota's legs finally showed up.
Mariota regularly gashed defenses with his rushing ability while at Oregon, but he's mostly been a pocket passer in his rookie season with the Titans.
That changed in a flash Sunday:
It's the third-longest run for a touchdown by a quarterback in NFL history, behind Terrelle Pryor's 93-yard scamper and Colin Kaepernick's 90-yard gallop.
