Whats the rewards?

Champion Mastery
Grades Hover over your Champion Mastery points bar in the post-game screen and you'll see the grade that our new system gives you. Grades are awarded based on your overall performance in the role along with the champion you're playing and, crucially, where you're playing them.
So basically I tought ill get rewards for having my champion on tier 7, but i dont get when and how. Im just gonna copy this here so u can see it too : Finish a game of League and you’ll earn points for your champion based on your team’s performance as well as your own contribution. **Earn enough points and you’ll level up that champ’s mastery level, giving you rewards as you progress.** What did they mean with enough points? Im really curious beacouse u know.... free stuff :D If anyone know's more than me please enlighten me.
