For all the schadenfreude, I think it's a bit of a beat up. It would frustrate RA that LSL (Lukhan Salakaia-Loto), Leota & Tupou (probably Pone too as a consequential effect) wouldn't want to be coming across, but the rest of the contracted group consists of:
Ethan Dobbins
Matt Gibbon
IAK
Angelo Smith
Vaiolini Ekuasi
David Feliuai
Matt Proctor
Lukas Ripley
Lachie Anderson
Darby Lancaster
Joe Pincus
Ekuasi and Proctor I would imagine are looking to negotiate releases, either back to NZ or to Japan.
Gibbon and IAK won't want to go to the Tahs because, presuming fitness, loosehead is meant to be a position of strength for the Tahs. I'd reckon this would also hold for Anderson and Lancaster, who'd want a clear run at starters jerseys rather than having to compete with the current Tahs back 3: again, a position of strength.
The rumours have the Brumbies happy to take Feliuai and Feliuai happy to go there: so I'm not sure why he's an issue.
That leaves Smith & Pincus (not listed as objecting to Tahs), and Ripley & Dobbins (would have to put in some serious performances to be anything but 3rd string at relevant sides).
