I get it and to use a Mayock expression I'm not exactly standing on a table pounding my fists for him and to use another NFL themed expression I think chances are better than not he won't provide a big payoff.I'd rather take the chance of seeing him do well on someone else's roster than waste a spot on my own with false hope.
But in terms of dynasty leagues and roster most of them allow for increased or unlimited roster space this time of year and his acquisition cost in most leagues is extremely cheap. So in dynasty leagues I think he's a great low cost speculative add, if he looks great in preseason you keep him and maybe you have something and if he looks like he did last year you cut bait and move on. This time of year that should have a minimal impact on draining your dynasty roster.
Same approach I'd take in redrafts leagues that draft early. I'll take a late round shot on him, if he looks the part great and if not I'll cut.
Bottom line is I would not count on him, I would not pay a lot for him, but I'm 100% on board with picking him up as low cost acquisition to see if he looks different in camp/preseason.
