For now, this just falls in the category of "Hmm...that's interesting."
Clement was appointed by Bush 43 as Solicitor General in 2004 at the age of 38 and regularly appears on Conservatives wishlists of SCOTUS nominees. Murphy is his protege and successfully argued the landmark McCutcheon Campaign Finance case before the Court, with Roberts, Kennedy, Thomas and Scalito in the majority and Breyer, Ginsburg, Kagan and Sotomayor in the minority.
I don't know what this means, but, before I dismiss it as just more bluster from the NFL throwing good money after bad, I am curious as to whether any of you who have been following this more closely than myself know which Judges from the Second Circuit have been designated to hear the case, if they have yet been designated? Clement and Murphy would carry a lot of weight with any Bush 41 or 43 appointees.
