Honestly SA isn't going to get market value simply because they feel they may be renting him. If I'm Cleveland, I go all in K.Love, their #8 draft pick, something else? As an NBA fan I actually want Cleveland to do what they can to get him even if it's unlikely. If they can get him in Cleveland, it may keep Lebron in a Cavs jersey. The Cavs probably don't have enough to get him, but I'd rather see him go there than anywhere almost. It would make for a much more competitive league, and not another super team. If Cleveland loses Lebron they're done anyway, they should throw whatever they can in a package and try to land him even if for one season.
The only problem I see is why would the Spurs want Love when they already have Aldridge? Also not sure the #8 pick is enough for them to reboot their franchise... they would want a player of the future going forward.
