The one that bothers me most, and has surprisingly been suggested by a few of my former H2H commishes, is having both CG and Shutouts as categories. That's gotta be the most ridiculous idea for a league that happens quite regularly (for me anyways). People always feel compelled to have either no CG/SO, or having both of CG and SO. Neither really belong in H2H anyway.
