In a recent interview with John Clayton of ESPN, Houston Texans linebacker said that fellow Texans teammate J.J. Watt has the capability of becoming the "greatest defensive player ever."

"The things that he's going to be able to accomplish are unbelievable," Cushing said during the podcast. "When you talk about the potential that he has of really being the greatest defensive player ever, he could be. I know that's very premature but he's that kind of player."

Watt, who is only 24, lead the NFL last year in sacks with 20.5 despite a serious elbow injury.
