Emmy winning actor, writer and comic Keegan-Michael Key ("Key and Peele") is host for this offbeat new series (based on an award-winning U.K. program) that celebrates sports. Two teams of three, captained by tennis champion Serena Williams and Super Bowl champion Rob Gronkowski, compete against each other in over-the-top physical challenges, absurd trivia and epic field competitions. The series also features comics Bobby Lee and Ian Karmel, along with guest sports stars and celebrities.
