O'Meara will want to play for a club in the 8 or in contention to play in the 8 over the next 1-2 years. Other factors are, the club must be Victorian based, must have salary cap space and have the capability to trade with GCS, whether that be for picks or decent talent willing to give up for O'Meara. Factoring in those considerations and coming from a common sense perspective:
Gee - Finals side is a tick however they lack the cap space and picks. I'm not sure they would be willing to trade a player with enough value and/or have a player willing to move to the GCS - NO
Haw - Finals side is a tick, picks are a tick however salary cap space is a question mark (I think they can manage their cap) - YES
WB - Finals side is a tick, picks a tick, salary cap space I doubt it - NO
NM - Have already ruled themselves out - NO
StK - In contention for finals next year, picks a tick and cap space a tick - YES
Melb - In contention for finals next year, picks an issue (traded their first to GC) and doubt they have players to move on to the GCS - NO
Coll - In contention for finals next year, no picks, no players to or willing to trade and salary cap space is an unknown. They do get linked to most players - NO
Rich - Not in contention and are rebuilding, picks and cap space likely a tick - NO
Car - As above but they also look to be bolstering their young talent through trading with GWS again - NO
Ess - Not in contention however gut feel is they will believe they are with players returning (but will O'Meara?) and picks and cap space likely a tick - MAYBE
Conclusion: Common sense suggests Hawks and Saints the frontrunners however clubs don't always use common sense and may make a play selling the idea they are on the up to O'Meara. Bombers a dark horse and there's something about the Blues too. They would be the four teams most likely IMO.
