Madrid has the easiest schedule. Even though they have one less home game than the other two contenders (Valencia and Depor) they only have one difficult game (at Depor). Valencia and Depor have more difficult schedules. Depor can't drop anymore points if they want a legitimate shot at the title. Honestly if they even get a draw they are out. Right now I'd say it's 50% for Real Madrid, 30% for Valencia, 15% for Deportivo, and 5% for a freak winner (ie. Celta, Barca, or Betis). Like always it will most likely be Madrid as the winner. La Liga is so predictable. The only other league more predictable is the Scottish Premiership.
Come on! Real only won 3 Leagues in the last 10-12 years. Way below "your average". Also, if Liga continues like it is now, it will continue to be more difficult to predict. In the past it was Real or Barca, but Deportivo won it 2 years ago, and Valencia might still win this, you never know.
