Out of the 3 mentioned, its a tuff call. Fletcher has to play at full-back, Gasper has to play at half-back, Hay has to play either positions. I would choose Gasper, only coz he has the more experience. In time Hay will be a legend at Glenferrie, but right now Gasper takes the points. Fletcher is a champion too, but lets not forget the calibre of his team-mates, at a lesser club he would probably be even better.
For the record, i voted 'other'... the person in my mind was M.Martyn..... with a mug like that, who would dare try to upstage him.... heheheehee
