Tom Brady accounted for five touchdowns in a profitable trip to Las Vegas. The coach he left behind in New England led his team to six points and a third straight loss. For those who accept the premise that the six-time Super Bowl champion quarterback left the Patriots to prove elsewhere that he was the backbone to that dynasty, well, he’s doing precisely that for Tampa Bay. Meanwhile, Bill Belichick’s current Patriots are adding credence to that theory. The Buccaneers have scored 222 points, topping the league, even ahead of the defending champion Chiefs.
