In the manga in the Tournament of Power, Roshi was able to dodge Jiren's attacks, if only for an extremely short amount of time. But to still be able to do that against someone so many magnitudes stronger than he is, well, it makes the fight that much more interesting as Roshi is on par with his opponent this time.
