I've only seen quotes from BSmith's interview, but did he mention things along the lines of "they wont be successful straight away... it could take them 5yr or so".
If that's the kind of mindset amongst players then it might be a hard sell for guys in their prime, especially if they're being courted by legitimate premiership teams.
Players get paid so much money nowadays that their thinking might be more geared towards success and prestige rather than taking the biggest paycheck.
It might be $700k and possible premierships at the rorters vs $800k and building a club from scratch.
Especially when Uncle Nick is flogging that he can turn that $700k into investment and being set for life after footy.
