My friend just started playing League, and he wants to jump straight to Ezreal, and I can't change his mind. Problem is, he still has no idea how to play properly. He prioritizes farming and jungling over killing champions. He tries to backdoor at level 1. He isn't there when a teamfight breaks out. He takes Heal-Revive or Heal-Clarity. He gets bush-ganked at level 1. He doesn't follow the recommended build. He stacks boots...Swiftness Boots.

Right now he's the poster child of a League of Legends Nooblord. What can I do to help him get better, and what are good champions that lead up to Ezreal?
