That's one reason. Other is that with so much speed boost choices in the game (Ghost, Talisman, RG, Sivir ult, Lulu's speed boost and your own ult), Olaf works as a battering ram, diving into the enemy team and crushing the carries and cannot be stopped. Even if you can't kill anyone, the amount of aggro you draw to yourself makes it that your backline can shred through the team.

Thing is you need to get ahead in the lane and snowball with damage items for Olaf to have that impact.
