What I mean by better fighter is that he developed certain parts of his game and fought with more strategy and patience. That's why he was able to do well with guys like JDS. That's being a better fighter. Ubereem and the guy who was off PEDs post the Lesnar fight fought the same way. From 2004 to 2011 Alistair had the same style. It was until 2013 after those loses in the UFC till he adapted.
You're just assuming, there is nothing to can prove this one way or another. You think this and I think otherwise whether he beats those guys on the juice.
I said UFC because the subject was his losses. You said this below....I am assuming we're talking about his losses to Ben etc.
All those KO losses you mention were not the version of Overeem that is Ubereem. If you had seen those fights, you would be aware of this.
Anyhow, there is nothing that make my view debatable. If you're hinting I haven't seen Reem crush a couple cans in Dream then I can assure I've seen all those fights. I've been watching Allistiar pre Pride. I can tell you one thing, when at his most Uber he faced a good Hw he didn't look so great. Remember the fight vs Werdum in SF?? Close decision, Reem couldn't hurt him and was slightly outstruck in that fight. Based on that performance, I think it's pretty safe to say Stipe would be fine to win that. From 08 to 11 he was just stronger, but same style, same defense and chin/recovery....Stipe finishes him.
