I doubt that Coley came here to run the exact same offense Fish ran. And Fish's offense looked nothing like Al's offense at Temple. I don't think Fish was merely a puppet doing what Al told him to do. I don't think Coley will be a puppet either. They might try to keep a lot of the same "language" with the Fish offense, but I don't expect Coley to come in here and run the same offense we saw last year.
One of the few times I haven't agreed with you chise. Jedd was brought in to design an offense for Golden. Golden already stated Coley won't be bringing in a new playbook here. Last thing Golden would ever do while building this program back up is have to put in a new system every time a Coordinator leaves. There may be some changes due to personnel strengths here and there but make no mistake about it that Coley is being brought up to speed and will then be the play caller. Jedd's offense may not look like Temple's under Golden but then again Temple didn't have the talent Golden has at Miami either.
I never saw anywhere from anyone connected to the situation stating that Fish was brought in to "design a playbook". I think that's an opinion that might have gained legs on message boards. My opinion, on the other hand, is that Fish was brought in to be UM's OC. Part of that job was installing a playbook. To say he was brought in here to build the blueprint for Al's offense for the rest of Al's career is not supported by anything I've seen.
I also haven't seen anything that supports the opinion that Al stated Coley won't be bringing in a new playbook. He was not part of the previous staff, was not a Fish "disciple", and I doubt that he'd have taken a lateral move for less money to be a robot stuck with Fish's playbook. This dude will have leeway to design plays and install plays.
I think we will try to keep the language as similar as possible to lessen the confusion with the players and make the transition easier. For instance, a guy like Gruden was famous for having such an intricate language when calling plays that it was almost impossible for young QBs to make it work. Al will most likely have Coley keep the manner in which plays are called and the nomenclature similar, but Coley will still have freedom to do his thing.
