During the course of the 2018 Philadelphia Eagles season, a lot of people said a lot of things about the team that would eventually go 9-7 and reach the NFC Divisional round of the playoffs. Some of the stuff made a lot of sense and turned out to be true.
Carson Wentz was clearly dealing with something that sapped his mobility and play-making ability. That something turned out to be a back fracture that forced him to miss the final three games of the regular season and two playoff games as well. There were some locker room issues with Wentz and Wentz himself admitted he might not have been the best teammate at times last year due to his focus on returning from his knee injuries the previous season.
