I guess the ref thinks that’s Tom Brady getting tackled.
It could be considered driving the QB into the ground but I’m not sure how the tackle happens otherwise. I saw a more egregious call in the Dallas Philly game. Hurts was tackled immediately after throwing the ball but the players were rotating and Hurts landed on top of the Dallas player. Yellow flag, 15 yards for tackling the QB.
That is what I hear the announcers imply.
I fail to understand how a 300 lb man is supposed to have the grace of a ballerina.
And, to be fair, many announcers are openly stating how idiotic the roughing calls have become.
