The article doesn't appear to have looked at how teams that play in the Sweet Sixteen and beyond in basketball facilities fared. I'm not saying it doesn't have an effect, but it is also hard to believe some of the effect they're attributing to the domes may well come from the competition. I'd also like to see a 2-pt vs. 3-pt analysis, which could lend credence to the sight line theory if threes are more affected than twos (or better, points in the paint).
