I hear you. It's maddening to say because as fans we all want to know what the heck is going on with our all pro cb, but this realistically could be a case where McD's "taking it day by day" is the truth rather than coy coach-speak. It's a risk/reward evaluation combined with many variables that we can only speculate on. We just have to trust our coach, the trainers and tre to make the correct decisions.
That being said, if he's not back in some capacity on or around 12/18 I will officially become worried about his eligibility in the future.
*fingers crossed*
Edit - aaaaaaand as I was typing this the news hits. Tre is active! Progress!
