However, in saying that in my opinion this season's challengers have generally cooked less appealing and less interesting dishes than in previous seasons. I think there are many reasons for that, from increasingly silly challenge requirements to changes in strategy over the years, etc.
As for putting out crap... I think many people (myself included) can succumb to the philsophy of "pushing food out as fast as possible because the chef is yelling at you" just to make them (temporarily) happy. Doesn't work most of the time but stress and craziness do strange things sometimes.
