Well, anything you take from BA you have to also remove from SLG so the player ends up profiling quite differently once you remove the Coors effect. Average is the one aspect of a slash line that hits OPS twice (once for OBP, once for SLG). Out of curiosity, I looked up the Rockies' team stats since 2000. It's kinda insane. Since 2000, these are the years the Rockies led the NL in home batting average: 2000, 2001, 2002, 2003, 2004, 2005, 2006, 2007, 2009, 2010, 2012, 2013, 2014, 2015. Since 2000, these are the years the Rockies finished in the top half of the NL in road batting average: ... It hasn't happened. They've never finished higher than tenth.
