On Sept. 15 (a new night!), Survivor will kick off its 21st season with a famous name and a big twist. Longtime football coach Jimmy Johnson will be among the contestants competing, and he's actually the second oldest castaway ever! Unfortunately he won't be able to rely on the strength of the youngins — this season the tribes will be divided by age! Find out who will be representing the elder team (Espada) and who's on board for the youngsters (La Flor) — all in their finest swimsuits, of course.
