The biggest challenge for Scotland will be dealing with the physicality up front I think. Ireland nullified France's advantage in that area by winning collisions, clearing rucks accurately, and generating unbelievably quick ball, while denying France any setpiece opportunities. There were only 5 scrums in the whole match, and that was down to low error rate but also looking to play advantage every time France made an error. I think Scotland have a good chance of a win, but trying to play at the necessary pace across their team is going to be a big challenge.
