With all the raging debates about level of play in the league of late, It has gotten a few of us thinking about whether there are any stats that might reflect at all on the overall level of play in the league. There are a couple stats that have been produced so far that might shed light on the subject: 1 - The cumulative save percentage of the top 10 GKs over time has tended to rise over time. 2- The cumulative PK conversion rate (PKs on frame) is up over time, to near-'perfect' the last two seasons. Of these two, they are both sort of indirect indicators. I think they both might say something about what happens in the league, but both only cover a tiny corner of what happens. I wonder if there are other stats that might help as well. I thought this thread might be the place for suggestions, and I have a couple to start us off. -- One other measure I thought of to get at a piece of the league's quality in an indirect way is the percentages of assists and goals teams get from their top one or two players. My theory is a Carlos Valderrama or Carlos Ruiz wouldn't be (isn't) as dominant as in the past not because they are inferior (arguing Ruiz '04 is weaker than Ruiz '01 is an awkward point to try to make), but because defenses are becoming more and more able to constrain any team's main option, so that they must find more diversity in attack. If this is true, then these percentages would be going down over time. It would be interesting to see if that's true. Another is the entire league's shot conversion rate in Shots:SOG. I think this might say a little something, but especially in conjunction with number 1 above. The objection to the SP stat has been that it doesn't take into account what kind of shots were taken. My objection to that objection has been that it strains credulity a bit to believe the league's shooters, as a whole, were suddenly shooting more tamely over the course of an entire season. But if we had the SC rate we might see whether the argument was even more strained--theory being that if SP has gone up and SC stayed stable or gone up as well, then clearly keepers' SP isn't getting better because shooters were getting worse. The only two meanings I could draw would be that they were either both getting better coincidentally, or that the shooters had all shot more 'conservatively' as a strategic decision, not because they were just inaccurate. (And even on the latter explanation, if that decision were taken in absence of considering the defense, then surely players over time would have 'learned their mistake' and begun to shoot more aggressively again). I figure I might take some time and look at these numbers at some point, but I wanted to bounce them off the denizens here, so as to see if there are others to consider, or some reason I shouldn't consider these. So fire away!
