I don't care about the two years age difference between Usman and Umar. They've got similar records. They've both beaten fighters with decent records outside UFC/Bellator (Umar's is better, so what?)
UFC get Umar, they give him a prospect in Morozov. At -400 he was still a significant favourite. If you're going to build someone, that's about right.
Bellator get Usman, they give him a 34 year old who is NEVER going to be an established main card talent in any top five promotion. He's a -1400 favourite. That's just dumb.
The excuse that Usman is 23, well, that's fine, but he already got eased in to the promotion against Mike Hamel - what's the point of the Muro fight?
Give him a youngish guy who poses a bit of a threat, is recognised as a good fighter, and Usman STILL probably wins and looks better for it.
It's not like you go on social media and it's awash with awesome highlight reels of all these fighters they've got smashing all this fodder, so what's the point?
Ranked fighter next time.
