My opinion is no: He has a win over both Volkov and Pavlovich already and he is about to fight Blades. Assuming he wins this, he will have a win over 4/5 in the top 5 only missing Gane. Since he has already cleaned out the top 5 of his division for the most part, he has plenty of time ( 5-6 years at the very least but could end up being more since heavyweights can fight up to and even past 40) to get both new names that get into the top 5 in the future, and rematch people he has already beaten that put together a good win streak. His biggest problem will be that this is MMA and especially in the heavyweight division, anything can happen that might change his life and career. His biggest problem is going to be can he get that many wins before people figure him out. Time is definitely on his side right now so he has a crazy amount of potential
