I've downloaded the historical db (Lahmans) and started my league in 1952. I'm wondering, in looking at the retired players list, there are a bunch of players that are very young (under 25) that are appearing retired that are not hurt. Example, pitcher Whitey Ford is 23 and shows in 100% condition but is listed as retired. Is this due to him being in the minors at the time I imported? Will he still make an appearance in the league draft? Can I do anything to ensure that him and other players of his ilk that are listed as retired are added back into the league for an upcoming draft?

thanks
