The MLB Network has a series called Prime 9. They have many topics like Prime 9 shortstops or All-Star moments where they have experts lists their top 9 in that category.
I watched the Prime 9 Players Not in Hall of Fame. I was just able to catch the tail end of it but saw that they had Mark McGwire at #2 and #10 at #1. If you don't know who #10 is look him up on Al's top 100 Cubs of all time and don't look too far from the best Cub of all time.
They had some ex players give testamonies on Ronny and hearing what his peers had to say about him really gives you chills. It is still beyond me why he is not in there and I for one won't go to Cooperstown until he is (I know that they won't care but it won't feel right to me). What was more astonishing to me was that there are only 10 third basemen in there as of now.
For those of you who do not have this channel I highly recommend finding out how to get it. If you've been reading BCB in the past 3 months you read nothing but good reviews about it and they are all deserving. For those of you that do have it you know what I'm talking about.
