Thumbs/Swipe

I'm not exactly sure, but it sounds like terms used in Buddy Ryan 46 coverages. I think SWIPE technique had a LB/OLB manning-up on an outside reciever. In this situation (pro formtion to the defense's left), the strongside corner would play deep half while the strong OLB would SWIPE and play man on #1. I think (but not sure) that THUMBS had the next inside LB responsible for the back to that side. If the OLB got a SWIPE call, he had to give the LB to his side a THUMBS call. Again, I'm not exactly sure.
