Those are numbers using the salary cap from this season, I believe. the new cap, whatever it is, will go into effect at the same time that the moratorium ends.
Jordan's been in the league for 7 years now, so he'll be eligible for 30% of the cap in his initial contract. The team with bird rights can give him 5 years with a 7.5% raise (on the initial salary) each year, while the other 29 teams can give him four with a raise of 4.5%.
