RAW after WrestleMania 35: 5 Opponents for Lars Sullivan following his debut
#4 Samoa Joe
While Lars Sullivan may have officially made his debut on the RAW after WrestleMania 35, bear in mind that there's always a chance that he could end up on SmackDown Live next. I mean RAW has enough big men as it is. There's also a high chance that US Champion Samoa Joe comes to RAW as part of the Superstar Shake-Up next week.
Whatever the case may be, I think it is all too likely that if Sullivan and Joe square off, Samoa Joe can potentially become a top babyface soon. Joe has the intensity and the fire to be someone that the crowd gets behind with utmost conviction. He can also wrestle as a babyface when he is given the opportunity.
We saw how he played the good guy during his feud with Brock Lesnar. I think a very similar feud can happen with Sullivan over the US title, that could enhance the US title picture significantly.
