As I watched the replay, all I could think of all the times that d linemen getting pushed to the ground and the ref throwing the flag. 99 % of the times it should not be a flag, but the refs blindly (ha ha) throw it anyway, just seeing the aftermath. The talking head refs on TV says they are taught to throw a flag only if the actually "see" the penalty, but they seem to guess on these plays. Makes me want to pull out what little hair I have left.
