I don't think it helps Maynard's case he hit Brayshaw who has had a history with concussion. That shouldn't come into it, but undoubtedly will.
From what I saw, the act was at worst, slightly careless in the sense he probably wasn't stopping Brayshaw's kick but it was a long way off malicious. Just because Brayden Maynard plays on edge does not mean he was trying to murder Brayshaw.
It's not about just stopping the kick it is pressuring brayshaw to effect the accuracy and angle of his kick.
You don't have to make contact with the ball to effect the kick.
