1 knee injury, not treated properly. same tendon/ligment, no further damage just delay on fixing it. Its not semantics, its facts. The rehab and horse sperm whatever thing he did is for weekend warrior types, not professional athletes. If the dolphins moved on from him because of it I wouldn't fault them because getting your body ready for playing is part of being a professional, see Tom Brady.
There's two ways I think Gase views RT17. Either he loves him and knows what most people with a decent football IQ think, and that is he hasn't been the problem with this team or they have him relatively cheap for what he is for at least another year and we did not value this weak QB class high enough to trade multiple picks. The best prospect as far as talent goes was Josh Allen IMO and I wouldn't even consider him before round two unless I was a team without a QB. I'm pretty sure it's option 1 based on the film from 16.
