In the Bills heyday of the 90's, when training camp was in Fredonia, I used to work for a company that rented them the golf cars during camp.
I got to be in the locker room for the first couple days and remember being in Abe Abrowdowski (SP?) office and seeing bottles and bottles of supplements, protein shakes, amongst other things.
I remember being shocked at the amount of different stuff and figured that was the norm for clubs.
Nothing to add I guess, it was just an observation.
I have no recollection of what they were specifically.
