This is kind of hard. Good fight. We've never seen Juggs get hurt. The dude can hurdle through think concrete without a scratch. Kitty phasing him into the ground didn't even hurt him.
I think it goes similar to her fight with Colossus. She beats him around a bit (without doing damage), while he just slowly chips away at her until he wins. Or he just charges her, tackles her, and keeps charging through shit until she's out. She cant really stop him if he gets moving.
