Been really liking what McDuling has put forward as well - just need him to stay in one piece! We need the ball-carrying and tackle-smashing grunt far more than a lineout specialist right now anyway..Kev, Simmo and Stiles will turn him good at set piece.
Was watching some clips of Kerevi as well as some of the older NRC matches for City and jeeze does he ever get low when he runs. It's not just that he's powerful, his center of gravity is almost always lower than the tackler as well - he lowers his entire upper body similar to how Brian O'Driscoll did when he would run the ball.
I honestly don't have any doubts in my mind that Hunt will come good too. Proven track record in the code and just a phenomenal athlete on the field and a top bloke off the field by all accounts. Has that all-around package (physical build, ball skills, no fear/hesitation, vision, kicking, quickness, acceleration over 10m) that you just don't find very often, a couple KGs off of being Nonu without the dreadlocks.
