He's been over hyped garbage for a couple years now. I don't think he will ever claim to be healthy since he is on the worst team in the NFL and there are no garbage teams to suddenly be healthy for and pad stats against.
He will be out of the NFL in a few years, the only thing that will keep him in the league longer than next year is his physical build. The browns will give him next year and then once they cut him another team will give him a chance and that'll be it for Garrett.
