Odell Beckham Jr. didn't have the personal success in 2019 he would've hoped for. That was the same sort of thing for Baker Mayfield, and the Cleveland Browns squad as a whole, for the most part.
Beckham should be given some slack, though, and he still wasn't exactly chopped liver. OBJ had a fairly underwhelming 1,035 yards, which was not up to his standards. Candidly, we were expecting more from Beckham, but him fighting through a sports hernia injury obviously didn't help his case.
That had to have been such a nagging ailment for him game-to-game, and likely affected his play.
