I concider a floater as someone who has no true alliance. Kevin and Michele had really no one they were totally loyal to and bounced to anyone with power and kissed butt. I respect a player who knows what they want, knows who to get rid of, takes risks in the game, protects their true alliance, and wins sometimes.
I try not to look at their game play and confuse it with their personal attacks. I may not like Natalie, but if I thought she was a good player, I would want her to win. I did not like half of the attacks Russel did, but he was a good player. He was wanted out for a long time and kept fighting.
I think there is more to be said for someone-like Jeff, Russel (even Jessie who I hate)- as a player and make it to the end after EVERYONE wanted them out for weeks rather than Michele, Kevin, or Natalie who have never been a real target.
