I don't know but if they don't rush Moses into a title fight he not ready for and he gains the proper experience he could well be the future of the division. Time will tell.
I'd favour the current Itauma to beat both a 19 year Wlad and the Wlad from his 12th pro fight. I'd favour peak Wlad to beat the current Itauma. It will be interesting to find out how good Itauma becomes in a few years time, when he's reaching his prime and hopefully fighting world class opposition.
Wlad was 21 years old and a former Olympic Gold medalist at that point so I would expect him to be further ahead.
