I sit five rows behind the team on Stanford's side of the field with the O-Line in front of me.  Due to the number restrictions for linemen and eligible receivers 1-2 players need to change jerseys when we run the jumbo package.  Rather than change jersey alone the team changes pads as well and there are always 3-4 pad/jersey combos with alternate numbers prepped and sitting behind the O-Line benches. 

Jersies are tightly fit over pads to eliminate opportunities for grabbing/holding so changing the whole set is probably easier than pulling on and off a tightly fit jersey .... but it's still not easy.  The player usually has two or three coaches and assistants helping to get the pads off, new set on and straps adjusted.  All of this within the constraints of a quickly ticking play clock.
