The coach likes Wentz better, even though Foles won the city the one and only Super Bowl in its history, and even though Foles salvaged the 2018 season and got them into the playoffs again, so there is no way they would have kept Foles and gotten rid of Wentz. Besides, the coach can always point to the fact that Foles is now injured, so he would not even have a quarterback if he had gotten rid of Wentz and kept Foles.
Wentz played reasonably well, so there is chance he can recover his old form of 2017. If not, then too bad for the city of brotherly love. The city booed Santa Claus once, and they may start booing Wentz.
