The only risk on Janelle's part is if either her or her players overplay their hand and make a push to reel in Shane prior to the POV ceremony. Shane is the best asset Boogie has right now as Janie's #1 target next week is Frank.
Willie could have been in the same position Shane is now in had he stayed. He'd have even commanded more leverage with Boogie being Janie's clear #1 target and with JoJo's vote as leverage. Sucks for him!
Team Janelle's plan with an HOH for her team or Danielle next week: nominate Shane/Ian, backdoor Frank.
Team Boogie's plan with an HOH for his team, Shane or Danielle next week: nominate Wil/Joe.
The Coach's competition would clearly throw a snag in one or both team's plans. Boogie can win them to protect Frank but Britney can't do likewise to protect Shane.
Taking out Wil or Joe makes too much sense to do this week. It's a shame Frank and Boogie won't consider it. Especially now that he has Shane wrapped up. He's gotten greedy.
