I'm saying the fact that he was a tryout player means that other teams weren't interested after the draft. Does tape in 4 preseason games change the opinions of any those other teams who didn't think he was worthy of a free agent look after the draft? I'd say that's a stretch. Beyond that teams will wonder why Green Bay, who are the only ones who saw him in practice every day during camp, kept 7 WRs other than him if he's supposedly good enough for their own active roster. If he's going to end up on a 53 man roster come roster cuts this weekend I'd guess it'll be with Green Bay or nobody.
But from Green Bay's practice squad he can be signed by any NFL team should injuries happen so his story is far from over even if he gets cut and he's earned every bit of that.
