A few words in Zach's defense...
I'm all about ED taking thee win, but I think Zach's been unfairly judged by some... He flew under the radar- that alone is a perfectly viable strategy (think Lisa). A young and toned guy like Zach always wears a target in the beginning. Quite frankly, I don't think he would've lasted long at all had he been more active.
I'm very annoyed that he didn't use the veto on Daniele when he had the chance, even more annoyed that he's talking about Dani and ED's game play as not being fair, and the most annoyed by his goodbye speech to Jameka- implying that he was her savior by "giving her a chance", but I do believe the guy has been playing from the start. He's winning when it counts.
