I think part of what makes Votto so good is that he approaches every at bat the same way. There is almost a robotic consistency and in general I think that is a good thing.
However, there were some situations last year where Votto seemed to be just going about his general approach which would maximize his own OPS and not necessarily maximize the Reds' chances of winning the game.
98% of the time, maximizing your own success/stats in baseball coincides with maximizing the team's success. However, I do think there were occasions where Joey didn't play good situational baseball and maximize the Reds' chance of winning the game by his approach.
Is it Joey's fault that the guys hitting behind him were struggling mightily? Absolutely not.
Is it Joey's fault that he didn't adjust his approach in some specific situations to take into account that the guys behind him weren't hitting and thus a walk was much less valuable than a hit? Yes, if his top priority is winning games and not his own OPS.
Just my opinion...
