Since joining the Dallas Cowboys as defensive line coach in January 2013, Rod Marinelli has played the role of mad scientist.
In a plush laboratory using limited body parts, he was tasked to create a ferocious monster with a bloodlust for quarterbacks.
The type of savage beast his 2002 Buccaneers became while choking the life from opposing offenses (12.9 ppg).
The same vicious animal his 2012 Bears conjured to steal 24 interceptions and rank 3rd in scoring defense (17.3 ppg).
The massive obstacle in Dallas was quality parts take time to accumulate and mesh into a violent entity.
