VIDEO: Cavs' Jefferson posterizes 7-foot-3 Hawks center

Welcome to the big leagues, Walter Tavares.

The Atlanta Hawks' 7-foot-3 center was introduced to the high-flying nature of NBA basketball, courtesy of Cleveland Cavaliers 35-year-old journeyman Richard Jefferson.

Cavs center Anderson Varejao grabbed an offensive rebound, Jefferson happened to be at the right place at the right time, and Varejao found him wide open for what turned out to be a ferocious facial on the Hawks' giant rookie.

Even more entertaining than RJ's dunk, perhaps, is the reaction from the Cavs bench.

King James approves.
