I'm not against the idea of incorporating the standings into this.
I want to make two important points:
1. We are going to select two players from each team. So, you might have say David Wright as the best overall hitter for the Mets, but Carlos Beltran as the "clutch" hitter. So, the standings angle won't have as much impact, since we're looking at two players from the same game.
2. The "multiplier" that I have in Leverage Index will only be used to denote thresholds. I will not be weighting a 10.0 LI game more than a 3.0 LI game. Basically, any PA with an LI of 2.5 or 3.0 and above is part of the "crucial PA" pool.
Now, if you want to argue that a 2.0 LI PA in the last game of the season has more "tension" than a 5.0 LI PA in the first game of the season, or a 10.0 LI PA in a game where you are ahead by 10 games in the standing, that's fine, we can do that. But, keep the above two points in the back of your mind. We are not going to try to distinguish between the contexts that David Wright and David Ortiz face. We are distinguishing between the Wright/Beltran contexts.
Sorry, I think I may have communicated my intent poorly.
RE: the distinction in your last paragraph, that's exactly what I'm looking for-- a way to look for performance differences during games where the season is on the line. With that in mind...
I will stipulate in advance that what I have in mind is completely unfair to potential clutch players on teams that do not breed "clutch" situations. The stuff I would be looking at basically excludes anyone on the Royals from consideration, because they never have an opportunity play in a "clutch" game (although they may have clutch moments in individual games).
BUT (and this is an important distinction, I think), I am not doing anything that would penalize them for being on a bad team, just saying that none of their plate appearances meet the criteria that we are filtering for. Kind of like if a hitter had never faced LHP.
So... what I am looking for is *not* Wright vs. Beltran, I am looking for Wright's production as weighted by the "clutchness" of the game. If Wright has not had many opportunities to perform in "clutch games," then we simply will not get a very strong read on him one way or the other.
RE: your point in paragraph 2-- What I have in mind is really just a sort of filter, or a way to produce weighted "splits" of performance in clutch/non-clutch games. It could be applied to any statistical measure in any way anyone saw fit. If, for instance, a game scores "1" on the clutch rating, then the player's numbers from that game go into the clutch column. If it scores "0" they go into the "regular" column. If the score is somewhere in-between, then the numbers are weighted proportionately (please bear in mind I still haven't figured out how to do any of this yet...

). "Multiplier" is a really poor word choice, now that I think of it, because it makes it sound like I am weighting the player's performance rather than the situation. I'm gonna change it in the original post.
In any case, I am not telling anyone what measure to use to evaluate a player's performance in "clutch games," just trying to identify which games are likely to bring out any hypothetical "Mr. October" superpowers. From there we can do whatever analysis seems like fun. Players who have been in more clutch situations will show more meaningful (but not necessarily better) results. Players who were never in a critical game will simply not make it to the list. My intent right now is just to collect a data set, not to define the best way to analyze it.
