Clowney getting to the RB level is a positive of course, because he's the first to get there, but I wouldn't consider it a "double-team" unless the RB specifically goes to him at the snap.
Duane Brown's first 2 years in league he was giving up double digit sacks. In his 3rd year the Texans game planned to have a TE, FB, RB help out w/ Brown's blocking assignment in passing situations usually w/ a chip block. As a result the number of sacks allowed by Brown dropped dramatically.
