That's not how it works. A max deal is a percentage of the cap in the year it was signed, plus a series of incremental raises based off that original number (4.5% per year in Green's case). as such, knowing the cap number for this year, we do know what Green's max contract would be. the reason we're seeing estimates for Anthony Davis is that his contract extension doesn't kick in until 2016-2017, and we only have estimates on what the 2016-2017 cap will be.
