I'm blaming him for thinking they have talent and having them on this team.
Kearns had an .830 OPS the year he came here.
Lopez was an AS SS the year before he came here.
WMP was a risk, but he did great when he showed up last year.
All are underachieving. You can't blame the GM for THAT, but you can blame him for not trying to trade at least two of them (and that's only if he hasn't tried).
