No. He totally blew his chances against Stipe and Ngannou. When he fights guys like that, who are younger and less damaged than he his, his fight IQ seems to go out the window. He knows he's always one punch or kick away from consciousness with his chin.
The "Econoreem" routine worked against guys who were older/slower than he is: Nelson, Mir, Hunt, etc. It almost failed against Werdum, and I think he was a bit lucky against JDS. That was JDS' worst fight ever--I still don't know why JDS didn't attack Overeem when he was briefly hurt and his back was against the cage. Prime JDS would've annihilated Overeem in that position.
