Which you obviously implied in your first post that he wouldn't have an issue with because of his fights with DC, seeing as you were the one to bring him up in the first place.
It went like this:
"Cain would beat Jon at HW"
"No, cuz he beat DC and DC was better than Cain."
"He beat DC at LHW and admitted he wouldn't fight DC at HW because HW is a different animal altogether. So saying who is better than who doesn't matter when you're talking about a different weight, and Jon said as much and most fans know that and know what MMA math is and shouldn't have to explain it by fictionally paraphrasing a conversation in quotes."
Besides, if we want to break down Jon vs Cain directly, we can take a look at Oct '12 when Jon said he was definitely looking to move up in 2013, then Cain won the belt in Dec, and Jon kept moving the goal posts on his "inevitable" move to HW for a decade
