I notice that when the Ravens try a FG they leave a very generic, non-distracting image up on the large scoreboard, but when the Chargers try a FG they have an active, live shot or some other distracting image playing. I do not think the latter is fair. Fans being louder, or jumping around (like in basketball when a guy is at the FT line) is fine, but manipulating the background electronically for the home team? Uh, no, it shouldn't be allowed.
