UAE going nuts from a get go and trying to kill/exhaust Vingo could cause Pogacar's fatigue at the end (also due to the Giro). Those two tiring each other may actually be advantageous for someone like Primoz.
However, the race is not just an "UAE vs Visma" battle.
Fortunately, there are plenty of spicy ingredients in the pot at the starting line
A good bunch of single riders and teams with goals to "go full nuts" during the entire first week.
UAE can easily gloat about it on the back seat, without having a decidedly active role, just awareness near the front pack and a few cuts there and there, maing a difference
Opens for slightly too interesting situations for Visma, with perhaps some hanging unnecessarily on the further back seat in e.g. split groups, where UAE naturally finds cooperative teams with stage wins in front of their noses and, hence, rub salt in the wound without UAE sacrificing the wild.
A lot of exciting possible scenarios here that require Visma to be extraordinarily alert, when Jonas arrive in Florence in e.g. 90% of max shape, but without any race training.
So maybe not directly UAE themselves, but then other teams will thoroughly test the uncertainty in unknown unknowns, or rather just go for stage wins amongst 21 other fresh teams in Italy.
