‘Every Bill has to weigh in and out of practice. For each pound he loses, he has to drink 20 to 24 ounces of electrolyte-packed fluid – possibly Pedialyte or Gatorlite, a Gatorade loaded with electrolytes. That means if a 300-pound lineman drops five pounds in a practice – which is not uncommon – he has to drink about 100 ounces before his next workout.’
