I have a theory with Tagataese. Otherwise known as Taggers, or as I like to call him, Tiggy Tiggy Tutu.
I don't think he was ever intended to play first grade for us. Not because he's not good enough, actually because he is a genuine first-grader who works hard and is a team man. With everyone kissing the arses of every young talent that comes through, they need some form of grounding. Enter Tagataese. Decent first-grader who may or may not pick up a spot in the 17 this year but every week is busting his arse at training, never letting his head drop, and happily doing his job in the ISC. The fact that he is going so well in that comp by all reports just reiterates it to the young guys - a spot in the NRL side has to be earned, over time, through hard work and commitment.
I'm sure during Origin, or through injury, or for a couple of select games, Wayne will play him to show the kids that there is a reward for all the effort. But he's here as a grounding influence IMO.
