As an outsider looking in i think it could be a case of Roby having too much pressure on his shoulders at the minute for you guys, as the reason why he hasnt been at his absolute free flowing best.
One by one over the last few seasons your big game playmakers have gone and as yet havnt been replaced with the required quality, or its a youngster finding his feet so its down to him to produce the magic.Another way to look at it is that teams now know if shut down Roby then you shut down Saints because there isnt another threat of the likes of Long,Pryce,Lyon,KC etc..
Anyway,i know who i want to see in the 9 shirt come the WC and it aint Michael McIllorum!!
