I don't recall the existence of any 30 day disabled list in recent years, but I kind of thought that there was a 21 day list in existence until fairly recently. The only thing I can really conclude is that there's no decent history of disabled lists on the web. Here's what Wikipedia says about the history of the disabled list: I don't recall a 10 day disabled list anytime in my lifetime, but the real problem is that because Wikipedia's history completely uncited, you can't give it much credibility. Information quoted on straightdope.com in 2004 comes from a personal website that's no longer in existence. Of course, this has the same citation issues as Wikipedia, but it seems to coincide with my understanding of the history at least a little bit: the 21 day list being dominant for a long time after replacing a 30 day list, with the 15 day list taking over in the past couple of decades. We need someone like JohnBriggs12 to chime in here. http://forum.brewerfan.net/images/smilies/smile.gif
