Four chances are

Judd
Tredrea
St.Kilda
Brisbane

Because there is no standout for St.Kilda or Brisbane,I don't favour any individual performance warranting maximum votes.
Haven't seen enough of Melbourne to know of Jeff Whites prospects,but it seems similar to above two teams.
Barry Hall could be a smokey,but does a bag of goals sway umpires more than a bag of possesions.
Work it out this way.
1 point in every round gives 22 points.Do that and you have a Brownlow medal around your neck.
Problem with Tredrea is,every time Port lose,he doesn't get any votes.Not so with Judd.
Gee,I've almost convinced myself to put more on him.
