Tyson had insane defensive movement.
FWIW, though, that move against Tillis is illegal. Tyson's head went below Tillis' waistline, and Tyson should have had a point deducted.
- Not that I really care.
As for vitali. He does still seem to have his defensive speed. He looked good against Charr's onslaught. (for 4 rounds, anyway.) It's his offense that is noticeably deteriorating.
