Maybe Einstein finally came to his senses and realized that yes, there is a slotting system; no, the Niners won't ignore it and piss off the entire league to make him happy; yes, he's losing money every week; no, the Niners can't trade his rights this season.
It's possible the investigation gave the Niners leverage. It's also possible that he's on the brink of losing one of his endorsements because of the holdout. The Niners have 5 passing touchdowns so far, which is about the league average, proving that he will get touches if he signs here, and that could also be a factor. Or maybe that November deadline is just getting too close. I don't know. I'm just tired of the circus. The best thing about signing Crabtree would be people shutting up about him for awhile.
