Just kind of cruising this thread and on a couple of points.
I don't think Wyc is mistaken, If I owned the Boston Celtics I would want to know what the overall cap strategy was.
Rondo's cap hold is for 6.2 mil.
Last year in an interview Paul Pierce said he was under contract for 5 more seasons.
KG went from a 23 mil option to a 16.5 mil salary when he signed his 3 year extension. Pierce is eligible for the same type of extension this offseason.
While it is only obvious to assume the economy will impact the cap it may not as quickly as you think as television contracts tend to drive the BRI. The cap has grown at 2.5-3 mil a season the last 3 years. These are the things Wyc knows that we don't.
If Boston knocks Pierce down to 16.5 mil and lets everyone go besides Perk(4.4 mil), KG (18.

, Pierce (16.5) and Bill Walker (850,000)they can likely squeek out another 16+ mil contract if the cap grows to 63-64 mil and 9 guys on the minimum (cap hold of 6.4 mil).
I only see this being done for Amare or Wade, maybe Bosh and obviously the King but lets get real. I think the threat of this may be as effective in trade talks as the reality.
