Um, yeah, that pretty much covers it.
Except for the fact that the Bengals' version -- the "sugar" huddle in particular -- was willfully designed to catch the defense with too many men on the field if they tried to substitute. That's why Levy complained to the league, and he was right. The K-Gun didn't need chicanery; with three Hall of Famers (and counting) on the field, they merely ran the defense ragged.
Oh, and <bleep> Boomer. One of my favorite Bruce Smith sacks was a decleater on Norman, after he'd moved on to the Jets.
