Reviewing the Supreme Court's work in sentence modification cases of Hughes and Koons

So much of interest has already happened this week, I almost forgot that on Monday the Supreme Court resolved two of the most notable sentencing cases on its docket this Term.  (Sentencing fans still have Rosales-Mireles v. United States on plain error review of sentencing errors and Chavez-Meza v. United States on required sentencing explanations to keep our interest the next few Mondays.)  Helpfully, I have seen on line a few reviews and round-ups of Hughes and Koons, and I figured it would be useful to link here:

• From Kevin Lessmiller at Courthouse News Service, "High Court Clarifies Eligibility for Reduced Sentences"

• From Jordan S. Rubin at Bloomberg BNA, "Justices Settle Sentencing Quandaries, Punt Bigger Question"

• From Justin Marceau at SCOTUSblog, "Justices clarify when prisoners can benefit from sentencing-guidelines changes, but refuse to revisit the narrowest-grounds test"

• From Douglas Berman at SCOTUSblog, "Justices discard game effort to extend eligibility for sentence reduction"

• From Carissa Byrne Hessick at PrawfsBlawg, "SCOTUS Term: Hughes v. United States and Federal Sentencing"
