It would be interesting to have a comparison of hand sizes or gripping area-strength in order to see if there is any ‘natural’ preference for under inflated footballs.

Well it appears he has small hands in all the videos I've seen of him. Thus he no doubt prefers smaller deflated footballs. Especially in rainy , snowey, cold weather. Plus , how many times have you seen a fast, hard thrown ball bounce of/ out of the hands of receiver ? Probably he catches a deflated ball, and grips it better for NO fumbles.
