Mixed feelings on this as I suspect it means either Jeff or Biyi are leaving, but given two weeks ago it appeared that Saracens were trying to sign him to replace Koch I'm delighted.
I agree it means we're losing 2 from Miller-Mills, Alo, Scholtz, TMA. Given we're getting Koch and potentially Ryan, I wouldn't be surprised if it Was TMA and Alo leaving. But maybe Miller-Mills or Scholtz is on a short deal. Keeping Alo (on current form) with the new signings would be insane depth.
That point about Saracens is very interesting. If Alo left us, perhaps that's where he'd go. And I recall other players, when they left us recently (e.g. Matthews) played as well as they did because they were free agents trying to garner attention. Maybe he's been told he's leaving and trying harder... Who knows?
