Not really. The head high contact came from a head clash, not body to head. The rules that the AFL has written explicitly give the MRO discretion with head clashes, even where they assess that a player intended to bump. I don't necessarily agree with how they've applied that discretion (eg the Burton case) but they are following the guidelines.
They have no such discretion to determine body to head contact is an accidental consequence of a deliberate bump. So the issue in the Simpkin case revolves around the assessment that he chose to bump. As already stated, I think he has a very good chance of successfully arguing he didn't chose to bump.
North have already been successful in one appeal this year and I reckon North fans should put their meltdowns on ice (can you do that) until a tribunal challenge has been unsuccessful.
Sandilands chose to bump. Simpkin had eyes on the ball, as did Christensen. Simpkin protected himself in the last moment, Christensen didn't.
