David Shaw doesn’t often show emotion on the sidelines. Saturday night was a different story.
Shaw got into it with San Diego State wide receivers coach Hunkie Cooper during halftime of the Aztecs-Cardinal game in San Diego.

This more complete video shows Shaw stopping an Aztecs player so Stanford could run off the field at halftime.
Drama at the half. If there's one thing coaches hate is the opposing coach coaching/directing your players. Shaw was reminded that.@XTRA1360 pic.twitter.com/xG2j3iujjd

It’s unclear what the issue was, but it seemed from that video to be about the way the teams left the field.
San Diego State was leading 10-7 at the time. Stanford was trying to avoid its second straight loss.
