Perhaps the most overlooked HF advantage we used to have was Kelly being able to read the winds. I remember times when the wind would just make other people look stupid, but Kelly's play never declined.
Looking at the stats, it appears JP has an advantage in the wind over Harrington. Some of it can probably be attributed to Chicago pulling down Harrington’s numbers, but at the same time it would make sense for him to struggle. He didn't play in any harsh environments at Oregon, Detroit, or Miami. Take a look at the numbers.
