I think Jonesy tries to spin out of trouble a bit too often and this is where he often gets caught. But he will get his head around this in time. Don't think he's diving, it's all attack and then a heap of lugs sit on him, and far too often now the attacker is getting penalised.
As far as tappering off goes, well he's 19, so the body is still young and he's playing in positions where you really have to bust ya gut. Reckon he'll have a solid pre-season and his general fitness will continue to improve.
I love him, love his endevour and love his bald nugget.
