‘General manager Brandon Beane said at his end-of-season press conference that he believes Stefon Diggs is still a true No. 1 wide receiver in the NFL. Diggs’ production at the beginning of the season was certainly on par with that. But from Week 10 on, he topped 50 yards only once, scored only one touchdown, and caught more than five passes only twice. Was it due to diminishing skill? Injury? Was it the result of Joe Brady‘s offense and play-calling? The Bills have to find out the answer to that question as they look assess the position.’
