1 x try from an offside marker who ran out of marker well before the ball had been played
Funnily enough they actually went to the video ref to check the last try. Pity he didn't notice that Burns went way to early. The Dogs should have had a penalty in front from 30 out.
Burns definitely didn't run out of marker too early - I think the replays had confused people into thinking that. They all started after the ball had been played and while Ennis was in the process of picking it up. Here's screenshots which show that he was behind Waterhouse after the play the ball was complete, and another that shows that he had stepped around Waterhouse to make the chargedown.
Angle 1 - 3 shots of the play the ball (start, middle and end) We can see Waterhouse at all times, a bit of field behind him and Burns isn't in view yet.

Angle 2 - This is the view they showed in replays, but unfortunately each of the replays started from the moment where Ennis picked the ball up. None actually had the play the ball. This is the earliest possible shot of this angle and you can see that in this angle just as Ennis is picking up the ball, Burns is in the middle of stepping around Waterhouse.

IMO the first series of shots show that the play the ball was completed and that Burns was still behind Waterhouse at the time, while the second couple of shots show Burns still in the process of stepping around Waterhouse as Ennis is about to fire off his pass.
Burns was just very determined to make that chargedown, and the time taken between Ennis firing off that pass and Kimmorley trying to line up the kick was just enough time for him to block the shot.
