He aint got nothing else to prove IMO, but he needs to think long term health. Surely he is already going to have later life issues with the injuries, no need to make the struggle worse.
No surprise whatsoever to hear this. That was a gruesome injury and Zach is lucky just to be able to walk normally. No way he was ever going to make it all the back to NFL caliber movement especially at his age. I do hope he can somehow stick with organization if he wants maybe as a TE coach.
It's such a shame because Zach was the best TE we had since Olsen when healthy but he just got hurt and hurt bad over and over and over.
