Wasn't it said that the deal was for 9M each year? Maybe DA is still waiting to see if it is worth risking future luxury tax penalties by giving him the annual raises for more financial flexibility this year.
We don't need financial flexibility this year. By my estimation, it's next year when we'll need the most flexibility to see if we can get under enough to qualify for the full MLE. After that, we pretty much have no shot at the full MLE in the 3rd year, and the 4th really is of no concern at this point.
So if I were Danny, and we have X figure to get to through the length of contract, I'd try to find the way to get the lowest figure possible next season, while still reaching X target by the fourth year.
Green's contract can only go up, or down, by 7.5% annually. If we're looking to keep his salary as low as possible next season, we could have him take a 7.5% cut next year, followed by raises of 7.5% in the following two years. The total value would still be the same.
Considering we're talking about a measley 675K, I doubt that is the holdup. Besides, with the contracts of all our other players likely to be of a standard nature, including raises of either 4.5% or 7.5%, I seriously doubt the full MLE will be available next year.
What could be of benefit, is keeping this year's salary a bit lower. If Danny is known for one thing, he's known as a guy who loves to make trades. We must stay under 74m this year, no matter what (CBA rules mandate it). If we wanted to take on a larger salary in a trade, every little bit less we have on the payroll could help.
