'Among the offensive veterans listed, T.J. Yates may have the best odds of cracking Buffalo's 53-man roster. Yates enters training camp as the favorite for the Bills' backup job due to his knowledge of the offense, but he's no roster lock. If rookie Nathan Peterman outperforms Yates for the No. 2 job, Buffalo may have to think long and hard about whether they rather have Yates or Cardale Jones as their third quarterback. Jones' upside could prove to be more valuable than Yates' veteran presence.'
