I hope he stays. From Ferentz saying in his press conferences that this is something that most do not have full knowledge off (me included, I hadn't heard about prior to this outbreak).
From the article it sounds like he will be out this year. No matter what happens, I hope he is well and things end up getting back to normal. I was looking forward to him stepping up this year given his experience.
Number 1, I hope he gets better and gets some weight back. Number 2, I hope he decides to stay and completes his career here. Those are the most important. I really hope he can get better enough to play this year and perform well to set himself up for a possible NFL career.
No matter what happens if he stays or goes, I hope he can fully recover and do what he loves to do.
