No. imo he doesn't beat either Jiri, Jan, Rakic or Ankalaev. He would have a competitive fight with Reyes and even then I would probably say it's a 50/50 fight. Adesanya relies on a big reach and height advantage.
Jan is a better striker than Adesanya, he proved that when he outstruck Adesanya over 5 rounds and checked a lot of Adesanya's leg kick, and it hurt Adesanya more than Jan. It had nothing to do with weight and is only an excuse after before the fight everyone talked about (including him) that it would be an advantage to be lighter.
Jiri is too big in his body and got more of a presence and is more powerful than Adesanya. They will have the same reach and Jiri would handle him with ease I reckon. Even if Adesanya is a very technical fighter, those big boys up in LHW are bigger than ever. It has now finally grown into an actual LHW division, when before it was filled with MW. There is a reason why Jon decided to avoid it at all cost now.
