Beat me to it. TP!
I've got slightly lower numbers for KG, Green & Bass though. Their reported totals were, respectively; KG-3 yr/$34m, Green- 4yr/$36m and Bass-3 yr/$20m. This would put their starting salaries, using standard contract stucture (7.5% raises), at; KG- $10.6m, Green- $8.1m and Bass- $6.2m.
I've also seen it reported, although not necessarily confirmed, that Smith and Christmas have a small amount of their contracts guaranteed. Not sure how much though.
Also, we can only keep 2 of the 3 listed of the non-guaranteed players, due to roster limitations (15).
My totals are:
69.6m-guaranteed (4.7m space)
71.4-including non-guaranteed (2.9m space)
My totals for the three signings are admittedly estimates, but when news of Green's deal came through it was reported as him making $9 mil in year 1, and presumably no raises each year. Considering they agreed to $9 mil for one year last season, this seems plausible. Likewise, Garnett was reported somewhere as making $11 mil in year one, and $34 over 3 (so I have him getting $333,333 raises each year.) Bass I just guessed on, but decided that a 6.33/6.67/7.0 structure seemed just as likely as the 6.2/6.67/7.13 structure that others estimate.
In general, I think Danny doesn't like back-loading deals/giving max raises when he doesn't have to, so I've gone with these figures. I hope that they're correct too, because we have enough space to do what we need this year, and the more paid now means less paid next season.
As a matter of planning, he'd be wise to avoid 7.5% raises for his own free agents. The CBA is structured such that the cap/tax levels will increase 4-4.5% per season most of the time, so 7.5% jumps will eat up bigger chunks of the salary pool from one year to the next, whereas smaller raises won't.
