well, the balls aren't left out in the pouring rain, are they? They are exposed to the conditions for a few plays, are swapped out, and toweled off.Which do you think more accurately depicts pouring rain in cold weather, spritzing a ball every fifteen minutes or rolling it in a pan of water?So, Syphers test was rolling a football in a pan of water, with no effort to towel it off.Can't find the original, but it has spread to a couple outlets.

Now we patiently wait for the people to point out that hes a Pats fan and dismiss actual science."The problem that they address in many places in this report is how to approximate conditions on the field, conditions in the locker room, and so forth all the various things that you don't know exactly," Syphers said. "(With) humidity of the rooms, they took a variation of parameters and temperature in a humidity-controlled environment and looked at that, and that was great. It's exactly what they should have done. The one place where they didn't do that was a wet football. They just used one technique."
If he were grading the Wells report like one of his students' papers, however, Syphers says it would have to be an incomplete.
"I would grade everything else they did there are little pieces they did of the sciences, and most of them I would give an A," Syphers said. "(The way they tested the wet footballs) I would give a D to, and because it's such a lynchpin for the final conclusion, rather than grade the whole thing, I would send them back and say, 'No, you've got to do this right. This is wrong.'
"If this were a professional paper being submitted to a journal, as a reviewer, I would tell them, 'You did not do this part correctly and it cannot be published until you address these concerns and do that right.'"
Exponent, on the other hand, sprayed the balls with water and then toweled them off.
I don't know about you guys, but I've seen ball-boys toweling off footballs when it's raining. I also didn't see any puddles in Foxborough.
Further, from the Exponent report (pg 48),
Ball condition (wet and dry): according to information by Paul, Weiss, the ballboys
from each team left several balls (up to four) in their respective ball bags during the first
half. Ostensibly, these footballs remained dry. Although rain was observed in the first half,
information provided by Paul, Weiss indicates that the ballboys kept the balls relatively dry.
Clete Blakeman recalled that though some, but not all, of the balls were moist at halftime;
none were waterlogged.
Obviously neither are perfect.
I don't see a problem with spritzing, personally. If I were running an experiment to simulate game conditions, that's what I would do.
