Let's see...
vs. Press - more turnovers expected. 6 games, 21 TO, 3.5 per game
vs. Zone - passing more important than BH, I presume, but small sample size (I guess that applies to this whole thing). 2 games, 7 TO, 3.5 per game.
vs. Man (good defender) - 4 games, 11 TO, 2.75 per game
vs. Man (so-so/poor defender) - 2 games, 5 TO, 2.5 per.
Repeating the sample size disclaimer! That looks about right, ratio-wise. I don't think I've ever started a D2 SF with passing anywhere near that low, and I'd say that's reason #1. Reason #1a is the top-10 schedule.
