I am sure that the locker room was not nice; maybe it does or does not have AC. I guess your offense did not use the locker room?
Considering LSU's library is in poor condition, but just spent $28M on their locker room, are you sure that LSU even has AC in the visitors' locker room? If it does, can LSU afford to keep AC running or in operable condition?

Just admit your defensive players are either unconditioned pussies, or your team uses unethical/unsportsmanlike tactics to slow down play.
