Projectivity. Ben has it in spades. No, I didn't just make up the term. EarlJam did. It's a long story, and as soon as he comes down, he'll tell it. (See his most recent Off-Topic thread.)
Projectivity, the ability of an individual to not simply see himself in the flow created by others but actually experience it, thus creating the ideal environment in which to perform maximally once you transmute into real world action.
So, Ben has the ability to imagine himself performing in exact syncronicity with the flow of the game he is observing in much the same way that some people who engage in imaginary practice of a task that they are adept at improve more than by actual repetitions.
Projectivity therefore would explain why guys like Ben and others before him perform so well coming off the bench, much better often than when they start.
But, not only that, projectivity would also explain Ben's lapses on defense. See, he gets caught up in projectivity while on defense. He starts being projective while watching the other team with the ball and, when what they are doing ceases to comport with the flow that he sees as having been developed, he gets lost, because he is where they should be instead of where they are.
Man, that EarlJam is something, ain't he.
