IMO, there is a far smaller chance to waste a brisket by using salt and pepper than by listening to a majority of the advice you find on the internet about cooking brisket.
Just go to youtube and search for texas brisket. You'll see all sorts of really poor cooking going on. Example, 22 hours in dirty smoke... blech. That's not Texas brisket!
