Guys get excited after big plays. When it gets out of hand, flags are thrown. That didn't happen.
Fletcher Cox regular does a crawl on his chest whenever he gets a sack. He hasn't had many of those this year (or last), but it's still his thing. He'll do it regardless of the score.
The 49ers were going against a QB who is hampered by a shoulder injury. No apology was needed for making it rougher on him. The Eagles couldn't throw. They were in trouble. When the 49ers made a big play, they were happy too.
