Yes, allergic to walks, but given the era he played in, it was probably more of a team style than a principled objection. It's kind of like Andre Dawson and Jim Rice not drawing walks. It just was undervalued at the time. Meanwhile, stats and eyeballs always had him as plus fielder, which James really did not credit in his early work but has come to recognize as having significant value. His WAR on FG was over two (average) for most of the second half of his career, and he had a few nice years sprinkled in.
