10. Tony Romo
Tony Romo might not admit it, but he certainly must have that “I should still be the starter” sentiment, as a member of this year’s Dallas Cowboys team that went 13-3. Ironically enough, this year appears to be his best shot at making the only Super Bowl appearance of his career, and if it were to happen, it’d be as a backup. Between 2006, when he officially became the starter for Dallas, and the end of the 2015 season, Romo threw for over 34,000 yards in his career, and made the Pro Bowl four times. But in the four playoff games he’s played in, his record is 1-3, with the NFC Divisional Playoffs being the furthest he’s ever advanced.
