#1 Should Not Be - Finn Balor

Given that Baron Corbin will be in the team, the former United States Champion will not pick Finn Balor at any cost. Even if the extraordinary man who does extraordinary things makes it to the team, the tension between the two superstars may affect RAW's performance.
Instead, Finn Balor could take part in either a mixed tag team match at Survivor Series where he could team up with Bayley to battle a mixed tag team from SmackDown or he could form a temporary alliance with another RAW superstar and win the RAW tag team championships in the coming weeks, to set up a battle with the Bar at Survivor Series.

Any of the above 2 options will be a better way to book Finn Balor, rather than having him as a part of Team RAW. As witnessed in the last year's event, his finishing move Coup de Grace was totally "no-sold" by John Cena and such booking decisions won't do anything good for Balor's character.
