First of all, I understand that I'm going to offend some people's delicate sensibilities just by posing this question. To those people, there's nothing I can do for you. The question has been posted, and now you're upset. You'll just have to deal with it.
To everyone else...
Suppose, for whatever reason, there was a head coaching vacancy at Michigan at some point before Lloyd gets too much older, and suppose Lloyd, taking inspiration from JoePa and Bowden, decided that he still had some gas left in the tank and wanted to continue coaching for a while longer.
Might you support his return? Why or why not.
