McCarthy stayed in his comfort zone. Didn't go outside of the organization. The Cowboys may take a step backwards. Especially with Dak being in one system for 7 years and now going into his 8th NFL season having to learn the west oast system. Remind me of when Troy Akiman during the 1998 season had to learn Chan Gailey system after years in the Don Coryell system. The Cowboys eventually went back to Troy comfort zone in 2000. It'll be interesting to see how the overall offensive players adjust to McCarthy scheme artlfter being in one system for so long.
