The Hightower strip sack was the same playcall as when Ninkovich stopped Lynch on 3rd and 1 inside the NE10 at the start of the second half in XLIX. Seattle had to settle for a field goal.
Right after this Patricia talks about the Flowers sack on Ryan. On that play Hightower gets mugged by Austin Hooper, and after the play Hightower complains to the official about no flag. Patricia said as soon as he saw that, he knew there would be a holding call if the Pats rushed again, which is what happens on the next play when Chris Long gets held to knock the Falcons out of FG range.
