Cejudo is near the end of his career and fights once per year. I'm not sure what you mean by a "run of good wins".
I am being honest. Watch Sterling vs Cejudo. There isn't much indication at all that he is washed up. It feels like you just looked at his age and that's it. You're saying he is washed up, explain why.
For you not to say he is a good win for someone to fight on their contendership basically implies that you think Kevin Holland level fighters can beat Henry Cejudo. He barely lost to the champion.
To put things in perspective, some recent fighters that have lost to guys who shortly after got title shots are Bobby Green, Neil Magny, Bruno Silva, Raulian Paiva, Johnny Walker, Thiago Santos
Cejudo is WAY above those guys.
