back on topic:
averages are a start... but distribution and volatility are required to give a real comparison... and definitely not based on small samples, like the ones above.
batted ball stats are a %$#@. good luck with that stuff. one website i go to only has info for the last 10-12 years or so. then, you have the problem of conflicting definitions of what a line drive / fly ball is, etc... at this moment in time the data is a bit murky and difficult to use in a precise way. i.e. you can get 2 data sets from the same period of time in the MLB and get 2 completely different results. so, what kind of integrity is there at the moment? not much.
