Maybe PFF was right that he should stay in the middle. I only saw 1 blitz up the middle, but his quickness seemed to stifle the guard much more than the OTs.
I have maintained for some time now that clay, and the defense as a whole, is far better when hes moved around. Hes solid in coverage, plays well in space, and making him be more multiple actually requires the offense to account for him. When hes on the edge, they simply slide protection to him and negate him most of the time. Hes wasted as an edge rusher.
