This one pisses me off every week.
Official throws a flag, followed by 1-2 more right after he throws it.
Hey assholes, just because you throw one too doesn't mean the call was obvious. These pricks have been schooled well by the league office. Whenever you see one of the fellas throw a flag, if you are in the area throw one too. Hey assholes, you aren't fooling anybody.
Cooper flagged for PI - it wasn't - on a flanker screen. 3 seconds after the infraction, after the guy is tackled, 2 more flags come flying in. Hmmmm, another penalty? Nope. Just tossing a flag because one has already been thrown.
If you don't see an infraction, keep the fucking flag in your pocket.
