The thing I want to make clear is that I appreciate that high correlation from year-to-year opens the door to a "predictive" stat. But, that does not mean that it is a particularly useful stat.
I suspect there is hardly a stat out there (on a team level) with as much correlation from year to year as "total outs", (not looking at whether they are defense or pitcher responsibility - just all outs). Year over year, total outs is going to be REAL constant. But, that isn't helpful in any way at all. Every team is going to get roughly 4300 outs per year -- every year. Highly predictive, yet useless.
