Cabrera should win it because 100 years ago somebody coined the term triple crown. If Cabrera was just the first player to lead the league in the three arbitrary offensive categories of BA, HRs, and RBI in decades, Trout would deserve it for being the better all-round player.
That isn't what happened, though. Cabrera will win the "triple crown", so that's more impressive than what Trout has done.
