Could someone provide stats that break down the error count into those made contesting the ball after an attacking kick by the Dragons and other errors.
Rather than crises Lomax for losing a contest, we should be encouraging him to do this and hope that his technique improves each time.
There isn't a specific breakdown to this degree that I know of. The only way you can do this is by watching every game through and mark down each error. And even then, it might be difficult to align exactly what the stats say with the game itself.
Although it's not enough to give a full representation of the year, I did it with the last game against Melbourne. The stats for Lomax say 5 errors and one 1 ruck infringement.
For the errors I counted 2 attacking kick challenges dropped, 2 balls dropped cold and 1 forced pass.
There were a couple of other handling errors like a dropped kick off and the missed try, but I didn't count those as this brought the actual errors above the stats and didn't fit with what I would say is a handling error.
Without going back through all of the games this year, I'd guess that it would around 50/50. 50% as a result of challenging for the ball and 50% unforced errors.
