Skip182 made the point recently that "Blues goaltenders this year have a baaaad habit of giving up goals in bunches. In games this season, Blues goalies have given up 2 goals in < 5 minutes 11 times, 3 goals in < 6 minutes 3 times, and 3 goals in < 10 minutes 5 times " Is that out of the ordinary?
First some fact checking. I get
10/12/13 NYR Halak gave up a ES goal at 36:56 and ES at 42:54 Blues win 5-3
10/15/13 SJS Halak gave up PP at 9:37 and PP at 10:25 Blues lose 6-2

11/16/13 CAR Elliott gave up SH at 35:37 and SH at 16:34 Blues win 4-2

01/16/14 LAK Halak gave up ES at 42:04 and SH at 44:21 Blues lose 4-1
01/21/14 NJD Elliott gave up ES at 2:27, ES at 2:51, and ES at 10:27 Blues lose 7-1
02/01/14 NSH Elliott gave up ES at 43:25 and ES at 47:33 Blues win 4-3
02/04/14 OTT Halak gave up ES at 5:52, ES at 7:02, and ES at 8:27 Blues lose 5-4
02/06/14 BOS Halak gave up ES at 49:16 and ES at 51:24 Blues win 3-2
So 18 games. 10 by Halak and 8 by Elliott. Blues record in those games is 9-9.

I only found 2 games where the Blues gave up 3 goals in less than 6 minutes. The third one is probably there somewhere and I'm just missing it. Taking those two games out, there were 5 games where the Blues gave up 3 goals in 10 minutes without giving up 3 in 6. (In one way of looking at it, they gave up 3 in 10 twice in the 11/29/13 game). Taking those out, there were 11 more games where they gave up 2 goals in 5 minutes. I'm going to look at the larger number for the 2 in 5 minutes below.
I looked at all regulation and overtime goals in 2010-11 through 2012-13 (no Shootout goals). The Blues were fifth overall in goals against over that time frame.

Just to make sure the Blues goalies weren't skewing the results, I took out the Blues games and looked at the remaining 29 teams. There were 16569 goals given up in 6148 games (2.695 goals per game). I pulled out how many times teams gave up 0 goals in the 5 minutes after a goal, how many times they gave up 1 goal in the 5 minutes after a goal, etc. I repeated this for the 6 minutes after a goal and for the 10 minutes after a goal. Obviously, there is going to be "right-censoring". There is no way to give up another goal after an overtime goal. Goals late in games also don't necessarily have full risk. Presumably, though, the Blues goals against this season reflects a similar mix of when the goals were given up.

Through 59 games the Blues had given up 134 goals. 1 or more goals should get scored in the next 5 minutes roughly 2929/16569 or about once every 5.6 goals. So that should have happened about 24 times this season. 2 or more goals should get scored in the next 6 minutes roughly 367/16569 or about once every 45.1 goals. That should have happened about 3 times. 2 or more goals should get scored in the next 10 minutes roughly 947/16569 or about once every 17.5 goals. So that should have happened about 7-8 times.
So the Blues goalies this season have given up goals in bunches less than the league average of the last three years. The Blues are an elite defensive team. How do they stack up against the 4 teams who have given up fewer goals?

Against elite defensive teams, 1 or more goals should get scored in the next 5 minutes roughly 303/1943 or about once every 6.4 goals. So that should have happened about 21 times this season. 2 or more goals should get scored in the next 6 minutes roughly 34/1943 or about once every 57.1 goals. That should have happened about 2 times. 2 or more goals should get scored in the next 10 minutes roughly 84/1943 or about once every 23.1 goals. So that should have happened about 6 times. For the big bunches (3 goals in 6 or 10 minutes) the Blues are right on the average for elite teams. For the 2 in 5 metric the Blues are a handful of instances less than the elite average.
What about the Blues the last two years? (This includes 33 goals from 15 games of Jake Allen in 2012-13)

2 goals in 5 minutes after a goal happened 35 times in 2 seasons. 3 goals in 6 minutes happened 3 times total. 3 goals in 10 minutes happened 10 times total. The expected total for an elite team are 42, 5, and 12 respectively.
If you look at goals scored in bunches, the Blues have a performance this season comparable to other elite defensive teams. During 2011-12 and 2012-13, the Blues were better than even the other elite teams.
