Back in December, Jay Glazer reported that Odell Beckham, Jr. was unhappy with the Cleveland Browns and wanted out of town. The player, and several of his teammates, have all disputed the report but once something hits the rumor mill, it's hard to get the speculation to stop.
As for OBJ, there probably was some truth to him being frustrated. Head coach Freddie Kitchens struggled to put together a good game plan and the offense was beyond inconsistent. This had an effect on Beckham, who was often ignored on the field.
With Kitchens gone and Kevin Stefanski now the coach, it would be logical to think that Beckham and the rest of the offense could be a little more optimistic.
