Last year, there was some wild movement in the NFL Draft betting market a few days before the event.
Aidan Hutchinson had been the big favorite to go first overall for most of the offseason, then the week of the draft there was a complete shift to Travon Walker as the favorite. Walker went first overall.
This year there is some more big shifts in the NFL draft betting market, but that's happening weeks before the draft.
Bryce Young was the favorite to go first overall most of the offseason.
