I think his experiment is flawed.

A deflated football has a smaller mass because it has fewer gas molecules inside of it. Assuming that the temperature is 32 degrees Fahrenheit (0 degrees Celsius), the mass of the air in a football inflated to 12.5 psi is about 0.39 ounces (11 g). A football deflated to only 10 psi has a mass of 0.36 ounces (10.2 g). The difference is about the weight of a paper clip, Eads said.
A difference so small should not make for easily reproducible results when humans are doing the throwing.
It was raining . The under inflated football was easier to grip .
So what does that have to do with the science experiment? His results supposedly show that under-inflated footballs could be thrown longer distances. Nothing about catching.
