Pitt @ Buffalo - Total: 40.5 Short and Simple. Chan Gailey has won 3 preseason games in three years. The Steelers are all about defense; in preseason week 3 Mike Tomlin’s Steelers allow 14.6ppg on average.The Bills focus in the off season has been all about defense. In 2009 the Steelers came to Buffalo for the week 3 “dress rehearsal” game and pitched a shutout (17-0). I expect something similar here and for this game to go UNDER to total.
