James Roberts kicking the Titans player whilst on the ground before the play the ball....Broncos score off the next play.
Try should have been disallowed with a penalty to Titans and Roberts in the bin for 10.
Blatant foul missed by on field refs should be called back.
There were 4 officials who should have seen that, is was blatantly obvious. They should have all been sacked for a week. The problem with using more technology is officials get lazy and rely on it too much rather than making a decision.
