The afl will revise the rules right before a favoured gill team stands to benefit from an easier get.I reckon it is harsh if your father son is one of the very best players in the draft because of that smaller top end discount. If I understand the points involved (and I'm not 100% sure I do), if you win the flag and you have a father son that would go #1 then it is very hard to match anyone who bids for him at #1. The discount means you're bidding with either pick 2 (with a refund) or pick 3 plus points from later picks to match. Its not easy to gather the points if your first pick is 22 (which I think was WC's first rounder last year). You finish top and give up your first, second and third rounder, and you're still nearly 1000 points short of being able to match the #1 pick, even with the discount.
I agree F/S shouldn't be a free hit, and the AFL are trying to balance their equalisation goals, but to align with the romantic spirit of the idea, I reckon a flag winner should be able to match a bid against a father son that is going to go very early, and right now it is pretty much impossible without trading for picks if that scenario arises.
