9. The New Day
If the plan is to get Brock Lesnar in for November dates as cover for John Cena, then a B-level feud that he could contest would be with The New Day. That narrative already has the foundation set, with Lesnar having battled Kofi Kingston at The Beast In The East. There's a ready made angle for The New Day jumping Lesnar for revenge. A really bold idea could be the group costing him at Hell In A Cell, although that's maybe too big of an angle for them. What would be fun, is if WWE booked the Lesnar versus New Day match at Survivor Series. It would be a one on three match, giving The Beast a battle to overcome. This would also represent a top feud for The New Day to move on to after perhaps dropping the tag titles to The Dudley Boyz at Hell In A Cell.
