The only part that worries me about that video, again, is when he says "you should see me run and do drills, you wouldn't even be able to tell I'm injured", if he was being coy, that would be a weird thing to say. I still feel like he's trying to make himself feel better about the injury, moreso than actual improvement in nerve regeneration.
But I'm assuming relying on a brace to help your foot drive off would lead to possible future injury issues (over compensating with other muscles). Playing with a boot would be worst case scenario. Would hate to see him in one.
