For D1, comparing the final year of BESR (2010) to 2014 with BBCOR, some stats indicate to me that small ball has barely increased, if at all.
Sac hits: Sac bunts per team per game are up from .58 to .76--an increase of about one additional runner advanced per team every five games.
But that's canceled out by the fact that--
Steals: Steals per team per game are down from 1.21 to 1.02--a decrease of about one additional runner advanced per team every five games.
Hit and runs: Impossible to measure. But if hit-and-run attempts have increased, then every time a batter swings-thru and the runner is safe at second, that would add to the stolen base rate.
Is the decrease of steals partly explained by a shortage of baserunners?
It seems not. Batting average is down 35 points, which implies a ~3.5% decrease in the # of baserunners, a decline which seems negligible in explaining the decreased # of steals.
Statistical analysis is not my forte.
What am I missing?
