I agree. I'm going to try both positions. I think Airflow might be better with pans in the lower part of the grill.So you think just putting it on the bottom is the best way to go? Wouldn't you still have the same issue of grease being right in the "line of fire"? Not arguing one way or the other, I guess I had just assumed it should go between the flavorizer bars and the grates so the grease is nowhere near the firepot. It would be interesting to try it both ways and see the effects on heat distribution and airflow, as well as if one way is more effective than the other for grease management and fire potential.
