Milwaukee Brewers's Prince Fielder, San Diego Padres' Adrian Gonzalez and other studs of the True Average metric - ESPN:
"There's a lot involved in turning hits, walks, total bases, stolen bases, caught stealing and other data into this batting-average-like form. We even build park and league adjustments into the formula"
How good is True Average if Adam Dunn is predicted to be better and Ichiro Suzuki worse? Of course, looking at the inputs points towards the biases of the metric.
