Saints will have the best first choice pack IMO, with Wigan the most depth. Saints' front row is certainly the strongest with Graham/Perry/Roby starting and TP/LMS/Moore coming off the bench.
Graham
Roby
Perry
Wilkin
Soliola
Flannery
Puletua
LMS
Clough
Moore
I expect big things from Magennis if he can stay fit too.
Rogues, I'm not sure how you can argue Saints' props aren't stronger than last season - yes we released 4 but one wasn't even being considered for selection when fit (Fozzard) and one was a shadow of his former self, barely playing through injuries (Mauire).
Best 5 props:
2010 - Graham/Hargreaves/Emmitt/TP/Clough
2011 - Graham/Perry/LMS/TP/Clough
No comparison.
