There were two incidents that I still think about from this past weekend.
One probably would have made a huge difference to the game's outcome; the Sco/Ire one where Seymour, looked to me to get pushed, as he offloaded that shitty pass to Maitland that allowed Murray in to score. Seymour had the ball so the push, if it happened at all, was legal?
The 2nd was when May was tussling with the French back on the ground and held him back by hooking his arm, effectively stopping him from getting to the ball before Farrell rushed in to touch it down. If that was overturned it wouldn't have mattered but it got me wondering how that arm hook was legal?
