Hobo and others, I'm not convinced that an agreement at 50% to 53% is really "conceding" on the owners' part.
Given that advertisers are looking elsewhere to spend their money, and fans might be looking elsewhere to spend their hard-earned entertainment dollars, methinks that it would be in the owners' best economic interest also to warm up a little bit more to a deal, if the financial numbers work (which I think that they do in the low 50's).

In an eerie parallel to the owners' threat to the players that the deal will get worse if they do not agree, the deal to the owners might get worse on the top line (revenue) when they try to negotiate advertising, etc. if they drag this out longer--not just losing $$$ for part or all of this season but also not getting as high of ad rates if advertisers think that the NBA brand has been tarnished with the passing of time (and/or with the irrational snobbery or bickering of the owners) or if the advertisers have already allocated it elsewhere. The NBA is probably decent advertising, but so is college basketball, college football, NFL, etc.--which is where these ad dollars are drifting to.
