The near-retirees should be pushing for a deal even more because they don't have as much time left. Exhibit A: Okur. Exhibit B: Raja. Haven't heard much from them--although MO is busy playing and Raja is probably busy watching movies.
Looks like Kobe, by contrast, doesn't care too much one way or the other. Then again, he has more overseas options than most other players, and he might like to spend some time internationally just to expand his legacy. (For Nike, etc., it's a partial win-win.)
Someone like Crymelo could potentially play during the full 10-year CBA so he does have more to lose by agreeing early, but only if they could somehow make the deal better by waiting.
Players are likely pushing for what would be a maximum of a (2%/50%=)4% increase over a 50-50 deal to 52%. I don't believe that the owners will give them one penny more than 50% of BRI, so it's fruitless anyway IMHO to not sit down and try to come to a 50-50 agreement.
Four percent of a ten-year contract is 4/10 of a year, which means that any stalling by the players is counterproductive if the lockout goes longer than 4.8 months (if based on a year; even less if it is based on the length of a season). Most players don't play 10 years, though, so a holdout of an even shorter period is counterproductive for most players--perhaps already the case.
Not sure if you start counting from July or October or November, but everybody definitely loses if the entire season is cancelled and the agreement parameters don't change. I imagine that the players get paid for the preseason, so they have probably already started losing out.
