A lot of teams are struggling with continuity this year. I can’t put my finger on it but the line speed over the 80 minutes is intense. Momentum is heavily influenced by officiating this season and it’s hurting a lot of sides.
I reckon changing the ball going over the sideline from a scrum to a play the ball has done that.
it used to be a valid tactic to give your players a rest while the scrum was packed, now there’s basically no stoppage.
