I just looked at a list of QB that would could be unrestricted FA if they don't get the tag. Drew Brees, Matt Hasslesback, Mike McMahon, and Quincy Carter were just some of the names on the list. Personally I wouldn't mind Bringing Mike Mcmahon on and letting him compete with AJ for the Starting Job. If anything he is a solid #2 who normally provides a spark when he comes in for Detroit and given an opportunity he may be a good starter and I don't think you would have to spend too much.
