agreed. Glad to see him improving in that area, but imagine that even with improvement he wont be a genuine jumper in the line-out; he'll be used sparingly.
Seems like Cheika has made improving Skelton's game a big focus of the Super season. He's giving him long minutes, and it looks like some work has gone into improving his set piece technique. Very promising Skelton appears, at least from the early games, to be getting his body into a better position in the scrums, and actually using his weight to drive forward. After another 10 rounds, he should be much more proficient than he was on the EOYT. Same goes for the Line-out. Cheika is certainly trying to get Skelton more involved, even jumping from time to time.
I think Chieka sees Skelton as important piece in our WC puzzle, and he's using the Super season to iron at the noticeably rough edges.
