Football teams today wear different jerseys for home and away games -many wear alternate jerseys as well- and we think nothing of the expense associated with these frequent changes. Back in the day, even big-time football programs pinched pennies, often replacing a dozen or twenty jerseys yearly, so it took a few years to get every team member wearing the latest style.
Did they wear old and new jerseys or was there a purpose as when teams had linemen wear helmets in different colors than their eligible receivers?
I know as late as ‘78 Clemson had players wearing different editions, at least at home.
