If Tony Romo (back) is unable to play against Arizona on Sunday, Weeden would start for Dallas. Romo didn't practice all week but was listed as questionable, making him a game-time decision against the Cardinals. Weeden has a strong arm and arguably good pedigree as a former first-round pick, but he's still a bust with accuracy issues, and he struggles to read defenses. Even against a vulnerable Arizona pass defense, it would be difficult to sign off on him outside of leagues that start two quarterbacks.
