WBA (Super), WBO and IBF champion Usyk is set for a rematch with Briton Anthony Joshua but, if he wins, could agree a unification contest with WBC champion Fury later in the year.
Scott backed Usyk, 34, to upset Fury.
"This Tyson Fury is much more vulnerable and easier to hit than any Tyson Fury before," he said.
Wilder drafted in Scott to help train him for his trilogy fight against Fury and Scott believes the British champion's change to a more aggressive style would suit Usyk.
