I think this is fair. The lack of information is equally as puzzling as the question(s). One likely begets the other. If we 'turn' the situation and Marrone offers some fluff answer and the reporters don't push the issue....we are calling them out for not being 'investigative' enough. In this scenario, they may have pushed a bit too much but there's a lot of variables. Reporters...and coaches...are human and allowed to have off moments. Either way, I didn't think this particular exchange was terrible by JW or the coach. non-issue in my mind.
Edit: Oh...and a foot 'evaluation,' with every imaginable resource available to him as a multi-million dollar athlete with the Bills behind him, shouldn't take 48 hours to complete. That's laughable. Give me a working diagnosis at least. Sadly, there is probably more to this story.
