McMahon doesn't play that way though. I like his intercept game, field kicking and athleticism. So far he is very ordinary defensively though. I hope he gets there but i'd be easing his development and third tall works that way.
Yeah my thoughts was to continue to mould his game over time looking at his 5th year not so much 3rd. I agree with his pros that you listed bit that athleticism should be able to see him come in late with spoils with reach much like DF did at Essendon. Avoids him having to use the body that needs a lot of strength work.
