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.
