There is holding on almost every play. OL are taught how to hold and hopefully get away with it. It's just boring when there is a call every 14 seconds by the BSC officials because of it...
As far as the Nancy "Targeting", there wasn't any on either play, and like the announcer that was in the NFL said, "That was a good hit 10 years ago"...
If they spear with the helmet, okay, but other than that...
Pretty soon, in some circles, they will be calling for real Flags on the waists while the players trot around listening to Mary Poppins... Back in the day, the likes of Butkus and Nitschke would rip people's heads off and it was just fine, no sensitive ninnies that would get their feathers bent.
The officiating was great for the most part, but the conferences were bizarre. I assume they have been in this line of work for a while.
