Pereira, VP of NFL officiating reviewed the RTP calls on NFLN, says both head contacts that triggered RTP are legit calls because it is much easier to control your arms than legs and there is no excuse for Ngata or Wright. On the RTP in terms of Brady's knees, he says two things: 1) Officials will err on the side of caution. It is far better for them to have a quick trigger finger on the flag, and absorb criticism than for a team to lose a marquee player or quarterback. 2) Addressing the claim that Brady coerced the flag/is a favorable player to protect, he says that no NFL officials want to be caught doing that because it affects their chances of being able to referee into the playoffs and someday calling the superbowl. Again those comments come from him, FWIW.
