11 is such a good number. There aren't many of those left. If he had worn 57 or 72, it'd be easy. But if he gets elected to the Hall, then it's pretty much guaranteed his number gets retired. I think it'd be more powerful to put his name on a banner, though. With all those numbers retired, his wouldn't stand out. He'd barely be remembered any more than he is now. If there's a COOPER up there, then everyone will be guaranteed to know his name and his story would be told often.
