Longo getting hired as the OC at Texas wouldn't be anything less than shocking. He has a good work history but I don't think FCS Offensive Coordinators find themselves getting promoted straight into an FBS Offensive Coordinator position right away. I'd say the same thing about Traylor but given he's already been with the program, it's far more likely that he'd get the promotion before we hired Longo.
I could see Wickline getting the solo OC duties. Or Norvell receiving a promotion to Co-OC with Wickline. Longo has been impressive in his time at the FCS level and I could understand why an FBS team would include him on their staff. But any team that did so would bring him in as a QB coach first and then allow him the opportunity to prove his worth.
