The 10th anniversary of NBC Sunday Night Football kicks off on Thursday, Sept. 10. To celebrate, the network had a 10-year-old girl named Isabella Day stump NFL superstars with surprisingly tough interview questions. Indianapolis QB Andrew Luck, Eagles RB DeMarco Murray, and Giants WR Odell Beckham Jr., were a few of the top players interviewed.
