FOX Sports 1 invited members from a Seattle youth football league to watch the NFC Championship between their hometown Seahawks and the San Francisco 49ers and proposed a challenge: They had to remain silent during the entire game. If they did, they'd get $5,000 to go towards their league (which desperately needs it). If they did not stay quiet, they lost and get nothing. It's not an easy task for the any part of the Seahawks raucous fanbase, known as the 12th Man. Check out what happened.
