He may or may not be. I think LA would like him back, he's a great defender but also not a real offensive threat.
Doughty is still a horse capable of playing big minutes, but the Anderson-Doughty pairing doesnt provide much offense either.
If LA got Rielly he could add some offense next to Doughty, and Anderson could be moved down next to Clarke or Spence. Or traded if Gavrikov is re-signed.
I've also seen ideas of LA trading Anderson+ for Byram, with the assumption that Byram plays with Doughty and Gavrikov is re-signed.
