#3. Becky Lynch purposely gets herself disqualified at Elimination Chamber
Becky Lynch heads to Saudi Arabia knowing that she holds all of the cards and the RAW Women's Championship is hers to lose. Lynch is a smart champion, which is why she has held the title for so long and has been able to overcome so many potential threats.
Most title matches in WWE involve the champion's advantage, meaning a champion cannot lose their title via countout or disqualification, and Lynch knows this. If Lita becomes too much for Becky Lynch to handle and she realizes that her title could be in jeopardy, then she only has to do something to get herself disqualified or walk out of the ring and get counted out.
This would allow the two women to wrestle again in the future and would ensure that Lynch was able to retain her championship. It's unclear what WWE has planned for Lita after Elimination Chamber, but if the WWE Hall of Famer becomes too much for Lynch, then it's expected that she could lower herself for these kinds of heel tactics.
