This guy is currently not playing professional ball as far as I can tell.  As late as last year the guy won nine games for the Florida Marlins, striking out 102 while walking only 62.  It seems like he's been around forever, but he's only 29 years old.  He pitched in one spring training game for the Pirates this year before being released.

Call me crazy, but why wouldn't any team want to give him a minor league stint?  Why not the Cubs?  It seems to me there's less downside and potentially far more upside here than with Edmonds...
