“involves challenges to the length of term-of-years sentences given all the circumstances in a particular case.” Graham, 130 S.Ct. at Graham is limited to juveniles. See United States v. Banks, 679 F.3d 505, 507 (6th Cir.2012); Jones, 476 Fed.Appx. at 652; Moore, 643 F.3d at 457. Walker’s attempts to differentiate his case are unpersuasive. That Walker’s sentence may prove to be an “effective[ ] life sentence” does not create an Eighth Amendment violation. “[T]he Supreme Court has never held that a sentence to a specific term of years, even if it might turn out to be more than the reasonable life expectancy of the defendant, constitutes cruel and unusual punishment.” United States v. Beverly, 369 F.3d 516, 537 (6th Cir.2004); see also Bunch v. Smith, 685 F.3d 546, 550 (6th Cir.2012) (<HOLDING>). Accordingly, Walker’s categorical challenge
holding that the eighth amendment forbids life without the possibility of parole for a juvenile who commits a nonhomicide offense holding that consecutive fixedterm sentences for juveniles who committed multiple nonhomicide offenses are not clearly unconstitutional under graham even when they amount to the practical equivalent of life without parole holding that multiple sentences for offenses under 18 usc  924c are appropriate when multiple separate acts of firearm use have occurred even if they are related to the same underlying offense holding that life without parole sentences for nonhomicide offenses violates the eighth amendment recognizing that njeither graham nor miller explicitly  apply to the functional equivalent of life without parole ie de facto life sentences
