yes immortal, i will miss those tries from dummy half and those charges wide of the ruck. but i don't think the first is about size. browny used to do the same when he played hooker and i think the coaching staff can find someone else to play a similar role close to the line.
saints have a big mobile pack and any one of sims, ryles, and young etc can storm out wide.
another factor to think about is the way ryles is used. with riddell gone i believe his effectiveness will increase. he runs well just off the ruck and i wonder if saints were seeing a flaw in the forward attack when riddell ran on his own too often? ryles can off load well something riddell didn't do often and everyone recognises the value of those short off loads. bailey does it well too.
i hope young steps up; he seems the one most likely to fill a riddell style role?
i don't think we need to get too worried about the loss of riddell. it would have been great for him to stay for the reasons raised by others; however, maybe we will see a more potent style of play all round.
