Did I suggest that swap? (genuine question... I don't remember, I may well have)
Ava is off contract at the end of the year - they may lose him (to us?) anyway. Tui isn't off contract until end of 2018 - a mid-season swap would give them Tui 1.5 seasons early, but only lose Ava 0.5 seasons early. They might consider it, if they actually want Tui - we'd have no reason to release him early otherwise.
I have a feeling they'll go elsewhere for a 6 though, and move Nofoaluma to fullback. The Tui->Tigers rumour feels more like 2+2=5 rumour-mongering than anything based in reality. There may have even been inquiries from the Tigers so they know their options, but that doesn't mean they're seriously considering a move for Tui.
As far as middles go this year for us, I'd be happy if they gave Pat Sipley a run this season. Not desperate for Ava this year - though we definitely need a prop (or two if we're losing Ben, three if Ben & Lillyman are going - Jake playing well though, I would look to retain him on a year to year basis) for next season.
