Not only that, they are also much less accomplished than Lou. Mattingly and Murphy don't even have any rings, so you can't make that argument about them.
McGriff would also normally fall short just on the merits of his career numbers, but I am guessing he will actually get a boost from being on the ballot with all the baggage guys there with him (Bonds, Clemens, Palmeiro, Belle, Schilling). No way any of those guys are getting voted in. I do think Bonds, Clemens, and Schillingwill all make it eventually, but as of today, it's just too soon.
McGriff is going to look like a slugging saint in comparison, so I would not doubt that he would be the only one to go in, if any.
