Brock Lesnar burst on the WWE scene in 2002 and within a few short months was the youngest WWE Champ in history, defeating The Rock at SummerSlam. He would hold the championship two more times and even win the 2003 Royal Rumble.
Yet, in early 2004, rumors began that Brock Lesnar would leave the WWE and try his hand at the NFL.
The rumors turned out to be true, and Lesnar wrestled his last match at Wrestlemania XX, in a loss to Goldberg. Both Goldberg and Brock Lesnar were on their way out of the company, and fans peppered both participants with jeers the entire match and, mostly, showed support for referee "Stone Cold" Steve Austin.
Lesnar's foray into the world of football ended with him being cut by the Minnesota Vikings. Fans expected Lesnar to return to the WWE, until the former NCAA Division I wrestling champ signed with the UFC in 2008.
Lesnar went 5-3 in his UFC career and won the heavyweight championship one time. During his career Lesnar battled intestinal issues and diverticulitis.
Though Lesnar had a relatively successful career in the UFC, the moment he announced his retirement from MMA at UFC 141 the internet was set ablaze with the possibility of a WWE return.
Anything can happen in the world of professional wrestling, and with that said here are the top five feuds I'd like to see, if Brock Lesnar returned.
