You might not be aware that the Cleveland Cavaliers signed Richard Jefferson this summer. The 35-year-old forward was an under-the-radar addition, and he might not be a regular part of their rotation. He'll be asked to occasionally hit 3-pointers and provide veteran leadership, but sometimes he'll also remind people that he's one of the best in-game dunkers of his generation. Look at what he did on Wednesday against the Atlanta Hawks:

Welcome to the NBA, Walter Tavares. Wow. 

It's quite something that Jefferson can still do that. Especially since Tavares is a legit 7-foot-3.
