Tony needs to retire but for me he started to be medicated after those weird meltdowns in 2019 and it changed him, slowed him down and he stopped having hallucinations in the octagon that would turn him into a fiend.
It is really weird if we think about it, dude goes nuts at home early 2019, steps away, comes back fights Cerrone probably in early stage of medication and a year after while being fully drowned in pills for the head, he fights Justin and gets f*.
Never seen a fighter just flip it like this.
