None of it makes sense. None of the moves SA made this off-season signaled an issue, LMA's play fit very well (especially defensively) and he's seemingly bonding with teammates just fine (commercials together unlike in POR where it was Lillard in big campaigns and no LMA).
He's close to his kid (which was a big deal) and the team is really good. There would have to be some major behind the scenes issues for this to blow up IMO.
It's possible with LMA - he's proven he can be a bit tough to deal with, but I just don't see it.
