In the boxscore of this game
(22222) only 27 assists are credited to the German players. But the sum of assists is 28.
In the play by play you can see that player Schrankl had 4 assists. The one assist with 0.02 to go in the 2nd quarter is credited as an assist to himself. I guess that's why he didn't get it in the boxscore.
