Secondly, ESPN is lazy with their salaries, and assumes that everyone gets max raises every year, which is something that Danny rarely if ever does with re-signing his own players.
ESPN may or may not be lazy about how they report player salaries, I have no idea.
The bolded part is absolutely false though. Danny had re-signed plenty of his own players to max raises. Pierce and Rondo are the first two that come to mind.
Also, I personally hope ESPN is right. Means we gave KG the lowest possible salary this season. Which in turn, makes it just that much easier to pull off a trade later in the season for a legit PF to replace Bass.
Pierce's salary decreases next year, instead of increases, so that would not be a max raise every year. Rondo did get one, which is why I said rarely.
Players who did not get one:
Ray (both his resigning and his offer that he declined this year)
Kendrick Perkins (extension he signed)
Tony Allen
Kevin Garnett (I think -- that was a confusing extend and trade, because there were trade bonuses included, but I believe his max raise per year was ~$2.7 mil, and he got $2.4 mil raises. Furthermore, he was negotiating with a player who wasn't on the Celtics yet, so it's arguably not even re-signing his own player for that deal.)
Glen Davis
Jeff Green's rumored deal is supposedly starting at $9 mil this year and worth $36 mil total
Honestly, Danny doesn't re-sign many of his players. But when he does, especially recently (I didn't look before 2005, because that was two CBA's ago) he has tended to not give max raises.
NB: I'm basing this off of basketball-reference.com salary data. It is certainly possible that some of their data is inaccurate, in which case I could be as well.
