Cavs acting general manager David Griffin said he wants to see the team smile more.

This play probably did the trick for the guys on the court - and the fans at home.

In overtime of the Cavs' win over the Grizzlies Sunday night, Dion Waiters storms by James Johnson, goes through the lane and throws the hammer down.

Cavs head coach Mike Brown called the dunk "huge."
