Dumont has turned himself into a topline runner and is very defensively dedicated. I basically think of him as being a poor man's Mitch Robinson as that defensive winger. Dumont doesn't impose himself onto the game or hit the scoreboard as much but like him could be a quality part of a functioning machine. Difference is Robinson is surrounded by better quality players. Dumont is one of many limited footballers in the North side.
Don't get me wrong Dumont is definitely AFL quality and would easily get a game on the wing at Essendon (Cutler, Ham, Langford, Zaharakis isn't a great group). It's just not really worth persisting with Mutch when Dumont would be a high level outcome for him.
