Esera Tuaolo pursued football with a passion that took him from Waimānalo to the NFL, where he played for the Green Bay Packers, the Minnesota Vikings and the Atlanta Falcons, among others, and made it to a Super Bowl—where he was the last man to tackle John Elway. In 2002, after retiring, he came out as a gay man. His latest competition? Singing on “The Voice,” at 49, having won a blind audition thanks to thumbs-ups from Jennifer Hudson and Blake Shelton.
