We don't know for sure, but I doubt there were any serious talks. My guess is that Breslow called, and LAA said 'Sure he's available. Arias, Witherspoon, Tolle, Early and some scraps'. The Breslow counters and LAA says' okay, keep the scraps, but we want your four best prospects'.
Seeing how LAA operates, I see no way they trade their best and most popular player for anything other than highway robbery.
