Federer played well, but I do think he's vulnerable on grass, and has been for a very long time. It's hard to describe but Zverev definitely was moving better, and there is an advantage of being young on grass. It's the suddenness and ability to accelerate that matters more so than raw speed.
Federer still has the wonderful shot making, variety and serve but he's been exposed at times by superior energy and movement.
I also think his forehand power is a problem, and in baseline wars he can be had if you can just hold out for a little while.
So he's the favorite, but It's not a super big disparity like he used to be or how Rafa is on clay or how Novak was on slow hards.
And yes, someone like Zverev can definitely win.
