The Ducks allowed two goals in the third period in a 4-3 loss at St. Louis on Friday, including the game-winner with 20 seconds left. But Anaheim has allowed the fewest third-period goals in the NHL (47). Under a different coaching staff last season, the Ducks also led in that category, allowing 59 third-period goals during the regular season. "Over the course of time, if you have a lot of the same guys, which we do, a lot of the core guys, you learn how to play in those close games and play with the lead," defenseman Cam Fowler said. "You have to be able to really clamp down, especially in the third, if you're going to win hockey games." Anaheim is 1-15-0 when allowing at least four goals this season, and coach Randy Carlyle said he has been emphasizing defense since the first day of training camp. "If you're going to be porous on the defensive side of it, you're going to have to score, and scoring is down in the NHL, and it's hard to score," he said. "The goals that are scored are basically either deflections or tap ins or second rebounds that are all scored under the 10-foot range from the net."
