I think I figured out who NCHawk5 is - Terry Brands. All the clues are there.
- Zero to crazy at the flip of a switch.
- Older guy challenging somebody to a physical confrontation, much like he did to Casey Cunningham after a Hawk loss at Carver.
- NC for national champion.
- 5 is the number of national championships the Brands brothers won when they wrestled for the Hawks.
