#1 Roman Reigns
Current situation: Roman Reigns was due to face Baron Corbin in the main event of the March 11 episode of Monday Night Raw. However, he was viciously attacked by Drew McIntyre and the match never got started. In the end, McIntyre defeated Dean Ambrose instead, while Reigns was attended to backstage by medical staff.
One-on-one history: Kurt Angle became an honorary member of The Shield at TLC in 2017 due to Reigns suffering an illness before the pay-per-view, but the two men are yet to face each other in their two years together on Monday Night Raw.
Possible match: Reigns is busy dealing with McIntyre, a long-term rival of Angle, right now, so they are probably more likely to team with each other on an upcoming episode of Raw rather than face each other. Still, the Hall of Famer is bidding farewell to Raw, as well as WrestleMania, so why not face its biggest star in a match built around respect rather than animosity?
