Evenepoel should start focussing on Jorgensen if he wants to win the TDF. He isn't going to be able to follow Pogacar and Vingegaard, so don't blow up your engine, and ignore them. Instead focus on Jorgensen, since he will be played out by Visma multiple times these next two weeks to attack early. All with the idea to make the race hard, isolate Pogacar, and make Pogacar close that gap. If Jorgensen and Evenepoel actually get away, they can work together to put pressure on Pogacar which is fine for Visma anyway. Until they get too far, than Jorgensen stops cooperating.
