That Raiders game was weird. Brown got called for PI four times and they were his only PI calls all season. Both teams had 14 penalties, and I don't think I've ever seen that in another game. Every other play was a flag.
But the same crew has done Cowboys games since then where not only were less than 14 penalties called, total, most of the flags were on the opponent (see Tennessee last year). So you can argue that they love the Cowboys if you focus on one game, or they hate the Cowboys if you focus on the other.
Me? Just don't do the dumb obvious things like blowing up the punter, false starting, or lining up in the neutral zone. Those flags are easy to avoid with any crew.
