Suddenly the Giro is the best preparation for the Tour.... that's BS. Roglic and Remco will not go to the Giro before the Tour. Vingegaard wasn't listed to do that. Certainly the performance staff of this teams know more about what is the best preparation for being in top shape during the Tour.
Suddenly Emirates finded the "Obélix magic potion", and going to the Giro is the perfect preparation for the Tour.
Pogacar was listed to the Giro because he and emirates doesn't want to risk an all in to the Tour, and not win 3 years in a row, a GT.
Pantani was the last one doing the double Giro/Tour, + 20 years ago. Since then, i never saw anyone being close to winning the double Giro/Tour.
Normally a top rider has the ambition of doing the double Giro/Tour, or Tour/Vuelta when in the previous year he won the Tour.
You can't win the Tour, but you think doing the Giro/Tour is more easy to being preparared to win the Tour....that's BS.
Pogacar just wants to go with the Giro in his pocket to the Tour, and ride without pressure. If he fails or fades again, he has the excuses of having the Giro in his legs. It's a win win situation.
If Vingegaard doesn't go to the Tour, and with Pogacar doing the Giro, Roglic has probably the last great chance to win the Tour.
