Trading Sale isn't going to happen. Not because he's untouchable, but because it's highly unlikely a team is going to bet the house on him. The price for a young, all-star pitcher signed reasonably for 6 years would be astronomical. IMO the days of teams going "all in" on trades are over.
That doesn't mean it couldn't happen, but the odds are long and recent history says otherwise.
