His advice ignores the benefits of leniency if you're guilty and you're almost positive you'll be caught anyway. For most of this discussion I've been focusing on the merits of talking to the police if you're innocent. But Officer Bruch also says that if people in the interrogation room answer questions and cooperate, then even if they're ultimately convicted, the police do testify to the judge that you were cooperative, and the judge can take that into account and reduce your prison sentence. That is at least theoretically another legitimate reason to violate Professor Duane's "Don't Talk To Cops" rule, if you're 99% sure that the police will find enough evidence to convict you anyway, you can hope for leniency by cooperating.
Would it not be more beneficial for your attorney to arrange some plea deal? As somebody who is not an expert on criminal law, I would keep my mouth shut until I talked to my attorney. I'd let the expert on criminal justice decide if it was worth confessing instead of hoping for the best.
