If the refs saw the shove by Draymond in real time, they would have assessed the T right there (after the fast-break ended). It had a high elbow thrown and was not a normal block-out/body-check.
Also Looney with the casual bitch ass shove from the back.
Seems like the nerd raging nephews are more angry that Dray got ejected than the fact it was just a common foul for Mitchell.
