Russell,
Basically what occurs is that any custom roster that is loaded will not display correct historical stats for certain players. (examples AROD with 202 hrs. instead of 556, Gardner with 12 hrs when he has 0, Swisher, Griffey, glavine and numerous others.)
Rosters based off the 3/23 seem ok. This was a problem with earlier releases as well but there was a work around up until the lastest SCEA official roster.

This is the work around thread.
