Akin Gump Strauss Hauer & Feld, Covington & Burling and Paul, Weiss, Rifkind, Wharton & Garrison divvied up the lucrative outside counsel work for the world’s most profitable professional sports league, which is awaiting the resolution of one of its most significant pending legal matters: litigation with former players who sued the NFL claiming that concussions and other head injuries suffered during their playing days had resulted in long-term damage to their health.
