How many in the league? And how many on the field?
Depending on how much you value this year's glory vs setting you up for the future I'd probably pitch for a) someone younger (Butters/Brayshaw/Serong/Green maybe? Dawson is 27 this year) or b) a (comparatively youngish) ruck like English or Darcy.
Or pick Sheezel and you'll be laughing for years
