Outfield Arm Study

An owner asked about the impact of Outfielder Arms.  There was an inconclusive study from a few years ago:

In a fictional league where the average team scored 870 runs, here was the impact from changing all OF arms:

902 R - 3 Pr Arms

890 R - 3 Fr Arms

870 R - 3 Av Arms

857 R - 3 Vg Arms

848 R - 3 Ex Arms

The study breaks down when you start looking at individual positions.  Changing the arm of one singlle player had a basically random effect.
