I agree completely. Ohara beats Derry -- probably by mid-rounds TKO, or a wide UD in a boring contest if Davies' laissez-faire performance in the Scarpa fight is anything to go on.
There are still unanswered questions regarding Ohara Davies' ability to hold a solid head shot. Anyway, if Ohara Davies vs Josh Taylor ever gets made at 140, Taylor would iron Ohara out.
