When it comes to MVP ask yourself honestly how much difference does Prescott make to the Cowboys' team?
Based on the previous two seasons where Cooper Rush has a 5-1 record as the starting Cowboys QB, there's an argument the Cowboys would have won all the games with him as QB this season (dominant defense resulting in pick 6s and offensive drive after offensive drive) except the Chargers game where Prescott was excellent and he played key part in the win by making some good plays when needed. On the same token the Cowboys may have beaten Arizona with Rush as a more regulation and competent type performance at QB may have got it done. The Eagles beat the Cowboys regardless so on balance Prescott has been worth one win over Rush in my view.
When I look at the Eagles' results then there's an argument Hurts was central to up to 8 of the team wins! Granted, he was a key culprit for the loss against a strong Jets D at home (Mahomes and Allen both struggled against the Jets D on the road as well). The four games the Eagles' opposition scored 28 points or more, Hurts and the Eagles offense scored more points and won all of those games with clutch plays when required. Conversely, the Cowboys' opposition scored 28 points or more in three games and sadly Prescott and the Cowboys' offense were unable to suppass that and lost both games.
Hurts made key contributions when the Eagles beat several very good teams in the Chiefs, Cowboys, Dolphins and Bills. He will have more chances to showcase his importance over the next two weeks when the Eagles play the 49ers and Cowboys.
It depends how people judge the league MVP but if the metric is the Most Valuable Player to a team, then if people are being objective, it's a no contest between Hurts and Prescott.
