Championship Flex Swift?

In my Championship match do people feel comfortable starting Deandre Swift at the flex?? With that said I also have AB as an option if he plays but the mid week re-injuring of the ankle worries me even if he plays. My other options for that flex spot would be E.Mitchell, Aiyuk or Gallup. It is PPR… Really appreciate any response to the topic FootClan!! Thanks… Happy New Year and good luck to everyone!
