As I said on the Leeds board, that’s not a bad side, I would fancy it over most in SL. The issues at half back can be mitigated by the fact Roby is such a quality player.
If I were saints fan my main worry would be that if that pack doesn’t win the battle in the middle of the park, it will drag players in and leave the saints smaller outside backs up against a big Leeds outside line, I would worry about the likes of Swift, Percival, Makinson, and Dawson, against the size and weight of Hall, Watkins, Briscoe. If leeds get a roll on, or get within the 20, it will be very difficult to keep those guys out.
If however that pack can set a platform and punch some holes (and a pack with Soliola, Masoe, and Laffranchi can do) then there is still enough speed and guile there for saints to put plenty of points on the board.
