IMO, Zach has no game play at all. He just reacts immaturely. It is just luck that he finds himself where he is. I think his assholeness is part real, part egged on by others. I do not think it is a strategy. I do not dislike him, but I just do not believe what he does is game play. He is playing with his emotions.
I may by rooting for Frankie, but yes Derrick has played the game the best. Kinda glad his game got blown up, but I am sure he will recover. It's amazing to me how people get when there name is thrown out for the block. Derrick acted incredously that he may be going on the block.
All in all, at least this season has gotten interesting. As long as Victoria or Calbe does now win, we will have a much better result than last year.
