I watched one of the games and there was also hardly any grandstanding. I recall mild grandstanding after a touchdown, but nothing after routine plays.
During one of the games, DC?, defense tipped a pass. ...the offensive center catches the ball....runs a few yards for the 1st down . ....then goes to huddle up, then quickly turns around and runs up to the line of scrimmage and does the one arm tomahawk chop pointing down field. ....then he runs back to the huddle. ...at the huddle he bobs his head “yeah” to his fellow teammate.
It was real funny. ...probably the only time in his career he ever caught a pass and got the first down. Really made me smile. He earned that tomahawk chop.
I think the NFL is overboard with self adulation. Like when the 49ers team celebrated with that end zone selfie. ..
