1. The newest news coming out is saying that McKinney will not be healthy in time for the start of free agency on March 3rd. The news points out that bringing him back for a cheap one year contract at the veteran minimum or close to it would not be out of the question...since he won't be healthy enough to garner major attention on the FA market. So, if we WANT him back, we can probably HAVE him back, at a pretty cheap price.
2. If we do lose him, it is safe to say it is because we didn't want him. And, if that is the case, where Hudson Houck and Nick Saban got their heads together and said time for Seth to go, why would you be worried about that? I trust them.
