FRISCO, Texas -- Since the 2016 NFL draft, quarterbacks Carson Wentz and Dak Prescott have been connected in many ways. Wentz, the No. 2 overall pick for the Philadelphia Eagles, has played with outsized expectations; Prescott, the No. 135 overall pick for the Dallas Cowboys, has outperformed expectations and become a preeminent pitchman. From 2017 to 2019, either the Eagles or Cowboys won the NFC East with Wentz and Prescott as each teams' predominant starter. Even as both watch Sunday's game at AT&T Stadium (4:25 p.m. ET, Fox) -- Wentz from the sideline as a backup to rookie Jalen Hurts and Prescott likely from his home -- they are viewed as a pair when it comes to what their uncertain futures hold. For the Cowboys, Wentz can serve as a potential cautionary tale of what can go wrong when the quarterback does not play to the level of such a gigantic contract -- especially as Dallas prepares for a third round of negotiations with Prescott's agent, Todd France, when the season ends.
