Maybe. I'm sure you understand that acknowledging that the string ends with a single identifiable bulb concedes the point. So we've got that going for us. Realizing that an answer exists is certainly the first step toward figuring out what it is. The first thing we would have to do is define terms because 'currently' doesn't really establish a timeframe for reference. Even if you wanted to go for the highest degree of illusory subjectivity and say it's one play, and how can you differentiate between, say, Brady's 99-yard touchdown to Welker vs. Flutie's hail mary vs. the fake spike and so forth? I would look at win probability deltas here, meaning the degree to which the play changed the odds of the quarterback's team winning the game. Then you would want some kind of clock adjustment; you don't want it to be inordinately skewed by the game state because that adds a lot of noise but you also want to retain some of that leverage as a reward for clutchiness and whatnot. Finally of course you need to difference out all of the other factors that led to the success of the play, which obviously is nearly impossible to do in any sort of principled systemic way. Now that I've written this it occurs to me as though I've basically answered it as one would one of those Microsoft-type job interview questions, which in itself I think sort of illuminates the point.
