As a mentor on the sidelines, my first reaction to this action on the field was, "Oh crap, they're going to card us." This was most likely because 16 got a red card 3 matches earlier for a pretty hard flip of 48.

You can see 48 playing a hard pin on 16 and the ref does nothing. 16 responds by bulldozing 48 into the courtyard. Red card.

We receive a foul for contacting a robot on the outerworks. We then hit 1296 while they're shooting. This goes against what Eric though, and what I thought I saw at the time (I thought we were both moving). However, it was a pretty quick hit.
I feel these two incidents are VERY different, but the head ref felt otherwise.
