I wonder if Wayne will look to try to help Smith to modify his game a bit now he's a bit older so he paces himself more and is less hectic which will then allow him to play longer minutes? Previously, he has gone at 100 mph for about 40 minutes and been very effective at least at Melbourne playing that go hard role in tandem with Harry Grant. But there's no reason he can't scale it back and be more of a 65 minute guy - if not 80.
Bit like how Dennis Lillee changed his game when he got a bit older and lost some pace and ended up being even more deadly swinging and seaming the ball both ways.
Smith is determined to play hooker, not lock and we need an A-list hooker whereas we are not short on locks that's for sure. Wayne is great at value adding players ability to become more versatile but in Smith's case, it ought to be helping him to play longer minutes I reckon.
