It's entirely possible - if odd - that he passed and they were just slow in reporting it.
I never bought the argument that this training camp and season represented a higher degree of external motivation for him to stay on track than he has faced before and failed with.
Going into FA, NOBODY doubted his ability as a running back. The only question mark whatsoever was weight. He knew it, his agent knew it. He could have shaved the weight following last season and certainly commanded a larger contract than the one he ended up with.
The day the Packers season ended to the day his contract was signed was the peak of external motivation. Right now he has 2.8 guaranteed and 2.8 in bonuses. Only 385k of those bonuses are tied to weight directly, although he surely must understand that his physical shape will help him reach the other goals.
But this offseason there were millions more at stake for him and it wasn't enough. And he had just gone through the hard-knocks experience of having a down year and Green Bay letting him walk because of it.
Learning isn't always linear; he may have eaten himself out of GB and out of a bigger contract but finally hit some moment where it sinks in that hey, there aren't an unlimited number of chances out there. The pessimistic side of me is just seeing a guy who has a real struggle with this. Wish him well for the sake of our team, and dearly hope to eat crow when he trucks his way through 2017, but when you have a problem that has already futzed about with your career to this extent, it's a pretty serious problem.
