Yer, he actually really surprised plenty with his mobility I reckon. It's a credit to him for the hard work he's put in, along with coaching of Ivan No.1.
The more I watch some of the replays ...(what's a man to do off season! ) the more little things ya see in the way he plays with a team first mentality, ie tap ons, shepherds, getting to the right spots in chains of play etc.
Still a kid in ruck terms and even if his progression slows, as a premiership ruckman he's got currency and a long career in the system if he wants it! Plenty of old draught horses on their 3rd and 4th list into their 30s!
