Free Step Dodge

There are many ways to counter it, low tracking moves(sweeps are good for this, if your character has a tracking sweep), low throw, low OH, mid tracking moves (although at certain ranges the roll will crush certain tracking mids, so use training mode to find your best mid tracking option), and contrary to your post non tracking strings will counter it, they just need to be fast (like honoka 6pk or 5pk)

Duck the OH from his side roll and low throw punish it.
