Well, it depends on what the definition of the word "sly" is.
It seems that over stepping ones Constitutional authority doesn't take much slyness at all, just intellectual laziness.
What Roberts did was usurp congress' constitutional authority to make law by rewriting the law to make it constitutional.
In order to do so Roberts had to redefine the word "penalty" to mean tax, rewrote the law substituting "tax" for penalty, then found the law constitutional because congress has the authority to levy taxes.
Without the rewrite, the law would not have been constitutional because the government can't penalize a person for NOT participating in commerce.
