Vision
Did you see that hole open to the left? Can you see the goalposts? Vision helps ALL players know what is going on around them. It is very important for QBs "threading the needle" with passes. It's also sort of the "6th sense" of predicting what your opponent is going to do when blocking or trying to break blocks. It also plays a role in avoiding penalties like false start and offsides.
