Casteel was hired by RichRod when he took the West Virginia job. He was the architect of the system for RichRod. Casteel was going to go to Michigan, but chose to stay then WVU hired Bill Stewart.

Holgorsen was hired in 2011, and Casteel was their that year, before leaving to go to Arizona to rejoin RichRod. Holgorsen hired other defensive coaches to keep running the 3-3-5.

The thing is West Virginia fans are misguided if they think Tech hasn't seen the defense. Bud Foster had success stopping it 15 years ago.
