Jennifer "Jen" Marie Johnson
Season 8- 8th Place
You may think I'm crazy for saying this, but Jen was good. She was a tough competitor. Despite everyone in the house wanting her out since week one after she cried about her picture, she survived all the way to final 8. She won the majority of the first half of competitions and each week she tried to make a new deal with a different house guest, but in the end her efforts weren't enough and she finally lost the PoV.
Note: This list is based purely off of gameplay, NOT likeability. Some of the people on this list I disliked in their season, but there's no denying they played a good game.
