Caleb Daniel 168cm
Jarryd Blair 172cm
(Both Premiership players)
John Noble 180cm
Not sure of your point naming two other small players, one of whom was derided his whole career.
I’m not writing Noble off but his size ( body mass not just height) is an issue. It will be interesting after a preseason in the gym. Given pace is his main asset there’s only so much you can do in the weights room without undermining his main weapon
