The 2009 cap figure isn't a good measuring stick because the owners opted out of the deal well before they even knew what that figure would be. They opted out before the 2008 season started, when the cap went from $109M to $116M. That was enough to unanimously vote to opt out. The 2009 cap figure was just like salt on a wound.
I factored in $27M based on the numbers from DeMaurice Smith. The owners figure was stunningly low, I agree, though the "final" figures showed them coming up quite a bit to $114M. However, that compares with the 2007 cap, when revenues were in the $6B range, not $9B+.
In 2005, the year before the previous CBA was negotiated, the cap was $84M. But the CBA deal changed the revenue formula, included all sorts of new revenue to split, and the cap went from a projected $94M to $102M in 2006, an increase of over 20%, and almost a 10% jump from what the previous CBA had forecast.
Which makes me think the owners were trying to reject all of the gains from the previous CBA, to pretend it never happened and start over. As a rough projection of 65% of TV/ticket revenues like in the old CBA, the 2009 cap would have been around $105 to $110M (with a zillion assumptions) compared to the $123M. Meanwhile, the players were offering a starting point that looked like the 2008 cap that made them opt out. It was lower than 2009 and what we would have seen in 2011 had the owners not opted out, but it wasn't about the 2009 figure so much as the owners hating the entire last CBA.
