A Lesnar return would be huge business for the WWE. I can just see him coming back onto RAW and taking control of the main event scene. He could be the big destructive monster that John Cena desperately needs to make his matches interesting. I can definitely see Lesnar coming in, wrecking havoc on RAW, taking the WWE title from Cena CLEAN, and then building Cena back up to the big rematch. It could be epic and I would love to see it. Not to mention the idea of Lesnar vs today's Randy Orton, the Lesnar vs. Triple H match we never got to see, and other possibilities like Lesnar vs. Sheamus and Lesnar vs. Daniel Bryan are interesting as well.
In honor of Lesnar's awesome push during his first few months:
