I was writing an article and was wondering if I should add some definitions. I am used to writing over at Beyond the Boxscore (stat heavy site), so I sometime find myself possibly writing too "stat heavy" here at Royals Review. We had a thread a while back where people could ask any question they want answered and I thought why not do it again. Let's go ahead and do it again. Here is your chance to ask about xFIP, SIERA, WPA or whatever acronym come to mind.
