If the receiving team thinks they're getting a rental because the rumors were already swirling that Texas was his destination, that'd reduce the number of trade partners... and because the new cap would mean very likely he was not going to sign a long term deal to be traded someplace he didn't want to go, the receiving team would have a UFA on their hands this summer, and he end s up in San Antonio anyway.
I don't think any team was desperate for a year of LA... but I'm possibly getting thing wrong.
