I suspect that Jayco will need to attack the final stage, They have Covi and Hatherly on 20 seconds and if they can get away, I doubt Ineos has the team strength to control.
Think the key to Groenewegens improved form is race selection. Like many sprinters he wanted to ride stage races because the mentality is you have 2 or 3 chances to win as opposed to a one day ra e.
It's very disappointing for Jayco who have a non WT level squad for cobbled races. They miss out on a rider who is WT standard at this level and they miss out on UCI points.
