Preheat oven to 275 degrees F and place rack in upper-middle position.
In a bowl, combine all of the spice rub mixture ingredients, and whisk together until there are no lumps.
Take a 9x13 baking dish, and criss cross half the bacon strips over the bottom of the dish. Set aside.
Trim brisket so fat is only ¼ inch, then use a fork and prick the brisket all over.
Rub the roast with the spice rub, until completely coated
Place roast on top of bacon in the baking dish, fat side down, and place the other bacon strips on top of the roast, tucking any ends underneath the roast.
Cover with aluminum foil.
Bake for about 4 hours, until a fork can easily piece and slip in and out of the beef.
Remove dish from oven, flip the roast over, place foil back over roast. And return to the oven.
Turn oven off, and let roast rest in warm oven for approximately 1 hour.
After 1 hour, drain juices off the roast, and set aside.
Remove bacon, and discard.
Combine reserved juices with BBQ sauce of choice, and heat in a small saucepan over medium heat. Cook until reduced about 10 minutes.
Turn oven on to broil, and place roast back into now empty baking dish. Brush roast with 1 cup of the sauce.
Broil until top is lightly charred and fat is crisp, about 5-7 minutes.
Transfer to a cutting board, rest for 5 minutes, then slice against the grain into ¼ inch thick slices.
Serve with remaining sauce.
