This description makes sense of how the Packers left the door open for Sherrod last year, PUP plus 3 weeks of practice off roster.

But has anyone read this elsewhere? Or does anyone know enough about this injury to confirm? Is it really just a matter of trust? Because I read that and immediately suspect we are in "fast healer" medical reportage territory.

The question with Sherrod is whether or not he can overcome the mental hurdle to trust a surgically repaired leg. In 2012 Sherrod was healthy physically, but unable to play because of his lack of ability to trust his legs to run, cut, and explode at full speed. This coming season will be different for Sherrod, as he will be more than a year removed from the injury and should be able to play as he did before the injury, giving the Packers a boost in pass blocking.
