There are definitely some plays when we all can agree someone was a bonehead. Forgetting the number of outs is clearly one--but also rare. Same goes for not knowing what to do with the bases loaded, 1 out, and a pop up on the fringe between OF and IF and therefore not called "infield fly rule" by the ump. When Leon was thrown out at home, JBJ did not realize he still could be forced out at 3b and was. This too is rare.
The problem comes, I think, on some of those other plays, especially those that result in outs, when a degree of subjectivity comes into play. The purists--my label,which might be unfair--would argue that stretching a single at the wrong time, going to 3b at the wrong time, trying to get home at the wrong time was simply bad baseball, even boneheaded. Even on defense some plays I don't consider boneheaded have been labelled so--thus Holt's hesitation and then bad throw on a force out at 3b from a bunt he fielded from 1b was to me simply a mistake, even a tough play. Others strongly disagree and say he should not have hesitated and, when he did, he should not have thrown to 3b. Me, I underwrite any mistake made when time is so short--less than a second--and the decision is pressure-filled (game was on the line).
Also, we seem to have no capacity to state that aggressiveness actually made a positive difference in any game,that Leon, for example, took a heck of a chance going home, which looked even worse when the throw actually beat him home--but he made a great "slide" and just got the plate without being tagged.
