Wr Hasise Dubois and QB Mason Fine are still unsigned.

I'm shocked and so disappointed for Hasise. I can tell you it's absolutely NOT a character issue - far from it. And I hadn't heard of any medical concerns.
He did have that issue as a first year where he was caught up in that bullying scandal where Anae's kid was running the fight club. I think he was named in the lawsuit. But I can't imagine NFL GMs would see that as a red flag given the lack of any subsequent issues and the fact that at the end of the day he was demonatrating toughness that he later showed on the field in big spots.
