This Sunday at Extreme Rules, John Cena will face Brock Lesnar in a match that no one thought was possible just a few years ago.
Although Cena was still at the top of the WWE then, Lesnar was at the top of the UFC as arguably the biggest draw in the company.
Yet, Lesnar retired late last year, and it opened up the gate for a return to WWE and a colossal showdown with Cena.
That match is just two days away now and will be one of the biggest matches in recent WWE history.
Thus, as you might expect, it will have far-reaching ramifications for WWE.
Let's take a look at what those ramifications might be.
