That meat looked awful lean before the cook. Also, I think you get a more tender brisket with foil. If paper is the cure all; why do cooking champions all use foil? For 60 years.
They also remove all the fat a lot of times. It's important to remember that backyard and competition cooking are two different things. If I cook a 15 pound brisket I would 15 pounds of great meat. In a competition their trying to get a few pounds of meat for the judges. The cooking styles are different. But, your absolutely correct, you do get a more tender brisket with the foil. The point of the paper is to help with the tenderness, speed up the cooking, and not ruin the bark with excess moisture caused by sealing in foil.
