The story is being overplayed and it is one very small part of the build up, that does not mean there isn't something small behind it in a few players minds.
By the same token, it doesn't mean there is anything behind it.
Revenge for last year's flogging is far more likely to be a motivating factor.
You could write a story suggesting that the Tahs are out to get Mowen for leaving the Tahs a couple of years ago.
Or that Dennis is out to get Fardy for taking his Wallabies 6 jersey.
Robinson is out to get Alexander for rucking him last year.
That Betham is out for revenge after the Brumbies let him go earlier in his career.
Or Hoiles looking for revenge against the team that had to let him go due to injury (this is getting a fair bit of a run).
There are so many possible stories you can write that don't need a shred of proof to back them up. They ask the player directly if it's a factor and they deny it outright so it becomes the player being tight lipped but secretly that's their motivation.
