I think these two sets of fighters are similar (inb4 explosive/athletic, "das racist gif", etc) in this respect: each set contains 1) an older/more experienced fighter who has cultivated a brash bad-boy persona, and 2) a younger/less experienced fighter who has tried to emulate the older fighter and has come up short. Mayweather walks out with Lil Wayne; Broner walks out with a budget version of Lil Wayne; Mayweather backs up his trash talk with a dominant (albeit arguably safe/boring) decision; Broner talks a big game, but looks impressive only against lesser competition/gets exposed against higher level of opponent. Rampage's chain is a trademark prop; Lawal also has a metal trademark prop, but wears it around his head instead of around his neck. Both made their name in Asia, and have had an up-and-down career in the big leagues in the United States. However, Rampage has honed his craft through years of experience, to such a degree that even though he appears one-dimensional on the surface, is actually a well-rounded mixed martial artist who can stay competitive despite the wear-and-tear/punishment absorbed throughout his career. For his part, Lawal has knockout power and great wrestling - however, just like other accomplished wrestlers at LHW (Bader, Davis, etc), he hasn't really evolved into a complete mixed martial artist. That is, he's either striking, or he's grappling, and if you can avoid the power shots and counter him (and/or anticipate his takedown), he becomes predictable and beatable. What can Broner learn from Mayweather, and Lawal from Rampage? That behind the bad-boy veneer, there is a combination of raw talent and years of honing one's craft; and that is something that takes time to develop, and cannot simply be duplicated through imitation.
