Alex Pereira defeated Strickland in the past and Adesanya made a comeback for his belt and won a great battle against Alex Pereira you can not blame them if they think that Adesanya can beat Strickland easily, as that Trash talking has got into him for sure Sean Strickland will still need to prove his worth, for sure that defense of Strickland really is effective against Adesanya for sure he is still enhancing that defense of him,
Adesanya was really lucky to win against Pereira. Overall, Pereira was dominating the match but Adesanya got a super lucky moment and a very lucky shot and knocked him out. Yes, Adesanya won it but we didn't see him dominating the match. Then we saw a very weak Adesanya against Stickland, Adesanya who was doing nothing in the octagon. Current Adesanya can't beat not only Stickland but many other fighters but old Adesanya can do it for sure.
Isnt this can be called luck, as he managed to dominate Adesanya for 4 rounds?

I just typed "best ufc striker", and among many tops, Adesaya was often among top5. Isnt it luck, if you beat best striker with simple shell defence? Isnt it luck to have a title fight when the last opponent you have beat was unranked guy with 1-1 record in UFC? Isnt it luck that Adesanya was not Adesanya and had mental problems (that is imho) that day? Of course Strickland improved, is a good fighter and no doubt he deserved that belt. But there were so many "little things" with Strickland and that belt, so I have called it luck.
Stickland is lucky because he faced the worst and weakest version of Adesanya, that's all.
