If anyone has other related ideas to suggest, shoot them in. Could be fun. Plus, this broadens the base for my potential constituency as well. As expected, volatility increased as a percentage of the average as player perforance declined. On an absolute basis, though, a trend in volatility is not evident, at least not in this small sample.
Pitchers do show more game by game volatility than do hitters.
In my small sample, closers seem to have proportionately more volatility than starters, but this is quite possibly due to the guys I picked. However, since a save is worth 40 SWP, and closers tend not to face many batters per outing, blown saves really do induce significant point swings - especially if a loss also results. That data is a bit unwieldy, but I thought it was at least illustrative of what we might expect this season. I'll leave it to you to suggest what the strategic implications might be. I'm not sure what the interpretation should be, because I expect the number of trades per cycle will be much greater for baseball, so that average price changes per cycle will also be higher.
