They'd probably be happy with either tbh. But Brisbane would be the better result for the comp I reckon.
At least Brissie are going to be top of the ladder and "earn" the monster homeground advantage.
Its better than it just being locked away at the G by default anyway.
Either they would be happy with, I feel they would lean towards GWS though. Especially if played at the GABBA.
The Lions win the papers will be writing about the 'gift wrapped premiership' the AFL handed to them.
