In training mode, if you play as Beowulf and have dummy set to ground tech, if you just go up and grab into finisher they tech properly, but if you do something like c.lk c.mp c.hp > j.mk j.hk > c.lk c.mk (grab stance) and then do a finisher the dummy will not tech the knockdown.
Edit: If you just wait out the grab and let beo do the auto-finish forward throw thing, the dummy will tech it.
