Lesnar's claim to being the greatest(if he never left)

In a video package a few weeks ago Brock Lesnar claimed if he stayed Cena wouldnt be around. On Raw this week we saw Lesnar in the ring with Hogan and a handful of Legends. This made me wonder where Lesnar would sit in terms of greatest wrestler of all time?



In my eyes, he'd definitely be above orton and around Cena's level in terms of current stars but I'm not sure where he'd rank in terms of all-time.
