Does a delay in reading a defendant's Miranda have the effect of coercing him to give a statement?

Defendant relies on Missouri v. Seibert (2004) 542 U.S. 600 [159 L.Ed.2d 643], where the police waited until after the defendant confessed to give Miranda advisements. Nothing similar happened here. Before the advisement, defendant was not questioned about the crimes and made no incriminating statements. The delay in reading defendant his rights was not used to coerce him, nor did it have the effect of doing so. A good deal of the time he was in custody before the interrogation, defendant was eating pizza. Any pressure defendant felt to talk to the police came from his father, not law enforcement. Defendant's arguments to the contrary fail.
