Since the Olympics…
The Red Wings have been held to fewer than 10 shots in 4 2nd periods and scored in 2 anyway. When facing at least 10 shots in a period, they have held their opponent scoreless in that period 2 out of 16 times. They have been less than 90% in 13 periods (at least one of those occurring in just about every game), including 5 1st periods.
The Red Wings have allowed 104 1st period shots for their 144 and gave up 12 goals (.115 against) for their 11 (.076 for). They fired 121 shots to 104 against in 3rd periods, going an even 9 (.074 for, .087 against). But in the 2nd period, the Red Wings have 1 more shot than in the 3rd, allowed 1 fewer, and gave up the same number of goals as in the 3rd (.087 against), while scoring 19 times (.156 for).
In the first two games back, the Red Wings played terribly in the second period, scoring 1 on 20 shots and giving up 5 on 20. Since then, they have scored 18 goals on 102 shots (.176 for) and given up 4 on 83 (.048 against), but have only scored first period goals in 3 games.
In third periods, the Red Wings have been held without a goal four times, have held opponents without a goal six times, and have only outscored opponents while giving up a goal once. They have not been outscored when scoring in the third.
The Red Wings have headed into the 2nd period trailing 6 times (1/2 of games), and have taken the lead in the 2nd period and given it up or nearly given it up in the 3rd period 4 times (1/3 of games).
