whoever the OC is, he should have free reigns find HIS personnel. Whatever way to be a successful OC. If Castillo interferes w/ his regime, he should be allowed to find a new lineman coach. I can't believe we just had to lock in Castillo that fast the moment season was over. Munchek just got hired by steelers. Couldn't we take a look @ a former HOF lineman w HC exp & 20year of lineman coaching exp?
