#2. Brock Lesnar
Okay, Brock Lesnar hasn't been linked with All Elite Wrestling, but we all know that Brock Lesnar does exactly what Brock Lesnar wants to do. What Brock Lesnar wants to do usually depends on how much money he's going to get paid. So in theory, if Khan opens his chequebook enough he could end up in AEW.
'The Beast Incarnate' is the current Universal Champion and is likely to be the defending champion heading into the biggest show of them all this year, WrestleMania. If that does happen it would be the third 'Mania in a row he'd do so.
This is exactly why he should never leave WWE and join another wrestling promotion. Because he's legitimately the top guy in WWE whenever he's there and in professional wrestling, there is no top spot greater than the WWE's top spot.
