I think they'll take their chances in that environment rather than playing an AFL league game. Its not fair to ask a player to do so either if within a few weeks of a potential AI Final. There is a lot of stuff written that players owe their club everything.
They don't. While they may spend their formative years there. They spend as much time from 14 up at elite level at county training playing against other elite players and developing their skills to an even higher level. Their clubs also get the benefit of that when they play for them.
As well as the hours that elite players put in on their own.
