Many people rather talk about FIP than ERA.
But how usefull is that stat? I know FIP ignores non home run hits and xFIP even ignores HRs so the purpose is to avoid fielding and luck.
does a FIP/xFIP lower than the ERA always mean that you are lucky? and does this equal out over a career (have there been guys lucky/unlucky over a whole career-or does FIP after several years match the ERA?)?
