I'm pretty sure he's a stat-nerd that can't get beyond the stats to the actual game of baseball. I think he's attributing way too much of the game to luck. Mostly because he's FIP-devotee.
Edit: That's how all these discussions go. I'm not big on the new, or old, fielding stats. Too many variables. I recall about 30 pages on UZR when it was the new, "hot" stat.
