I agree with you, but this guy has not looked good since he KOd Matt Brown in 2016. He deserves total respect for his dedication and contribution to the sport but comments like these only reinforce the notion that he is a year or two past retirement and is just trying to cash in at this point.
There would be no problem with it, if he was not still ranked #6 in his division despite winning only four of his eleven fights since that Brown KO. Not to mention two of the last three guys who KOd him are fighting for an interim title next week and the other is actively campaigning for one.
So while you may laugh off this comment, if history is any indication Pettis might suddenly be in line for another title shot if he KOs Cowboy like his last three opponents have.
