We had a difficult week in Iowa. We didn't have a good car in practice but we made some changes that we thought would really help. Today the car was 100 % different than yesterday. The car was extremely loose from the start and we were trying to make changes in the pit stops but none of those changes worked. I don't really know what happened when we crashed. I was just trying to hang on and make it to the next stop so we could make some changes. The car was still extremely loose. I was lifting the throttle big time in Turn 1 and, all of the sudden, it snapped on me. I tried to correct but there was no chance to correct. It was a big slide. It's too bad for us, but we have to start focusing on Richmond and make up some of the points we lost today.
