The 2017-18 curling season would not be as successful for the Smith rink as the previous season. The team began the season by failing to qualify for the playoffs in the first two slams of the year. They found success at the 2017 European Curling Championships, where they went 6-3 after the round robin, and beat Switzerland's Peter de Cruz in the semifinal before losing to Sweden's Niklas Edin rink in the final, to win the silver medal. At the 2018 Winter Olympics, Smith led Team Great Britain to a 5-4 round robin record, putting them in a tiebreaker against Peter de Cruz of Switzerland. This time de Cruz would get the best of the Smith rink, advancing to the playoffs while Great Britain would have to settle for fifth place. After the Olympics, they faced off against Scottish champion Bruce Mouat and his team for the right to represent Scotland at the 2018 World Men's Curling Championship. Mouat won the event, and would go on to win a bronze medal. The Smith rink ended the season by making it to the quarterfinals of the 2018 Players' Championship. They did not win any tour events that season.
