The overlap between the Cleveland Browns and Philadelphia Eagles is almost completely related to one man: Andrew Berry. Berry spent one year with the Eagles after time in Cleveland before returning to run the Browns as their general manager. Berry has often spoken of his time in Philadelphia and what he learned from GM Howie Roseman.
While the Browns and Eagles won’t match up in Brazil as many expected, the two teams have spent time together in joint practices.
Berry certainly learned about aggressive, as he talked about in his press conference after being hired, from Roseman.
