Add up the salaries of Pierce, Rondo, LMA and Batum and that puts the team at:
Pierce: 16.7 this year and 15.3 the next (player option)
Rondo: 11 next, 11.9 the year after and 12.9 the year after that
LMA: 14 million this year, 15.1 and 16.2 the succeeding years
Batum: likely to be 8.5 on the low end and possibly as high as 10.5 on the high end ... for 4 years.
That's a helluva lot (about 51 to 53 million) of committed salary for 4 guys for the next couple of years and at least 9 other roster spots to fill (including a center which isn't ever cheap) ... so yeah, that is going to be a luxury tax team or at the very least a team that has zero flexibility with a group of players that probably pushes them back into the mix for a playoff spot, but probably doesn't push them to WCF contention, let alone finals contention.
In terms of bang for the buck, that doesn't excite me much
