7. Sheamus
WWE.comDespite any criticism that Sheamus receives from fans, the fact is that he is a tough guy in the ring. He throws the heavy hands with the best of them and has been in his fair share of fights. But so has Roman Reigns. Now imagine these two men facing off. They crossed paths when Roman was in The Shield and recently at Money in the Bank. Fans got a glimpse of what a feud between the two men could be and it was worth their time. Standing toe to toe with The Celtic Warrior is something that not many WWE Superstars do and Roman could be one of the few to hold his own. Trading punches with Sheamus, proving his mettle with every blow struck, this would quickly remind fans that while Roman may have a very marketable image, he is also one of the toughest guys in WWE. He would go through a trial by fire with Sheamus and if he was still on his feet in the end, it would be a stamp of approval on him. Many fans have been begging for Sheamus to turn heel again and having a feud with Roman could be the best way to make that happen. Roman's popularity would certainly outweigh the pop that Sheamus is getting and a feud between them could be beneficial for both men. Sheamus would be established as a real heel threat again and Roman would add a three time World champion to the growing list of victims on the way to the top.
