The old posting rules were a huge advantage to bigger market teams, obviously. As others have pointed out, the new rules don't seem to help this at all.
Why not do this: Keep it the same as the past, with the postings secret and the highest bidder winning the right to negotiate with the player. However, add the posting fee to the luxury tax so that teams must factor this in. This would be a disincentive for bigger market teams, but not one strong enough to keep them from participating in all circumstances. You could also have a mandatory amount count against the tax for all teams that bid, no matter whether they win the bidding or not. Something small, like say even 3-4 million, would make bigger market teams think twice about bidding on a player since there would be a tax/cap penalty no matter what, while smaller market teams wouldn't care since they aren't at or close to the tax threshold anyway.
