Those who see Houston Texans defensive end J.J. Watt's dominance up close and personal on a regular basis are running out of superlatives.

Texans defensive coordinator Wade Phillips predicted after one season that Watt would end up with a Hall of Fame bust in Canton. One year later, Phillips touted Watt's second season as the best in NFL history by a defensive lineman.

Texans All-Pro linebacker Brian Cushing has taken the Watt plaudits to an even higher level, suggesting the reigning NFL Defensive Player of the Year could rewrite the league's record books.

"The things that he's going to be able to accomplish are unbelievable," Cushing told ESPN.com's John Clayton last week on the "Inside The Huddle" podcast. "When you talk about the potential that he has of really being the greatest defensive player ever, he could be."
