#3 Should Be - Alexa Bliss
Alexa Bliss was set to face Trish Stratus at WWE Evolution in a dream match, but her injury led the match to be turned into a tag team contest with Mickie James joining her to battle Trish and Lita. However, she could not recover to full fitness, which resulted in Alicia Fox taking her place.
But Alexa seems to be recovering quickly now and could be a part of Team RAW. If she is able to step inside the ring, there is no reason why she should be left off the RAW team at Survivor Series.
Bliss represented Team SmackDown at Survivor Series 2016 before participating in a dream "Champion vs Champion" match against Charlotte Flair. Though Alexa lost both matches, her involvement in Team RAW in 2018 will boost their chances of winning the contest, as Alexa is multi-time women's champion and has always received strong booking from the Creative team.
