You could be right, I've not seen enough of him to really comment. From Wigan's point of view though, the last thing we need for next season is blooding another young prop.
Spencer, Crosby, Burke and Taylor have all been first teamers this season having had hardly any top level experience. Even Dudson and Flower are in their fairly early 20s and only in their second season at the club.
Outgoings are Prescott (27) and Mossop (24) leaving only Lauaki as a proven, experienced front rower. Even if Pettybourne isn't top class, the sort of pedigree you get playing for Souths could well complement this group of freakishly talented kids.
