How is his wrestle? Where's his contact in D- is he locking up the ball? How quick is he up off the ground? How quick is his PTB? Is he tying in back behind the ruck or is he giving away cheap metres, LBs and quick PTBs? How's his line speed when he's fatigued?
He's a long way behind Vave in terms of numbers in their final years of NYC IMO. Vave was absolutely dominant in the NYC. Second best prop in his year behind Merrin. Taupau, Tasi, Sims and Clayton likewise. They were all averaging 150m+ and 20+ tackles a match. Just going off my recollection of Viiga's stats (so could easily be wrong) he'd be more like 80-100m/match and 15 tackles which wouldn't put him in anywhere near the same class of workrate.
He needs time IMO. At least one year of NSW Cup. A chance to take Ross' spot down the track though. What's the use of throwing him in there early anyway?
I haven't seen him be offloaded on to many times this year AB. His first contact is NRL standard and there is nothing wrong with his line speed. He looks to offload and plays through the advantage line almost every time. He isn't getting alot of game time so it's hard to get a guage on his fitness. As I said, he is still a bit raw but the talent is there if he is coached properly.
