Former Pittsburgh Steelers defensive tackle Joe Greene loves to watch Texans defensive end J.J. Watt.
Greene won four Super Bowl rings with the Steelers. He's a two-winner of the NFL Defensive Player of the Year Award, and he's a member of the Pro Football Hall of Fame.
"He's like the Tasmanian Devil," Greene said Sunday night at the Special Olympics fundraiser. "He's all over the place. He's moving and moving and moving and making tackles.
"Whether he's at tackle or end or right side or left side, it doesn't matter – he's making plays."
Watt, who's entering his sixth season, has something Greene doesn't: He was voted NFL Defensive Player of the Year for the third time in February.
