Brock Lesnar Reportedly Hated John Cena When He Was With WWE

According to PWTorch, when Brock Lesnar was previously in WWE
(nine-years ago) he did not get along with John Cena. Stories from
behind the scenes say that Lesnar was not a fan of a young, up and
coming Cena. One source actually stated, "Brock absolutely positively
hated and detested John Cena!"

Lesnar reportedly bad-mouthed Cena
to Vince McMahon many times, especially anytime Cena was doing
something being perceived as positive. It is also said that the feelings
"came through" if you watch body language in their first pay-per-view
match in 2003 at Backlash.

During that match, there are many
moves that look sloppy, and at the time it was believed that it may have
been an outright intentional lack of cooperation on Lesnar's part. Some
feel that with Cena on the rise, and the animosity that Lesnar felt
towards Cena, that it would not have been out of the question for Lesnar
to make Cena look green and clumsy. That is a reputation that Cena had
at the time, and one that he was working to overcome.

I guess he really did 'rise above hate.'

One thing's for certain... that makes for an interesting story line.

Maybe Brock knew what ab overhyped piece of shit cena would become and he wanted to stop it.

He was mad because of Cena dissing the mess out of him during their feud on SD! back in the day.

Cena never would've been this big if Brock had remained.

You don't know that.

Cena was already beginning to gain popularity before Lesnar was on his way out.

Yeah, it's hard to theorize anything by playing the 'what if?' game.
