If you look at the graphic below, you can see the receiving statistics for the top 10 passing teams in the league, as well as the Bills stats. Eagles. But as a 2nd receiver, his numbers are not adequate. A number closer to 900 would be desired in a 2nd receiver.
2. Roosevelt was our team's next highest performer last year. His numbers make him the worst WR3 on this list as well.
3. None of this would really matter if we had a dominant TE. New England and New Orleans each get by with mediocre WR2 and WR3 because of the precense of a truly dynamic TE. Our Bills... not so much. Chandler's numbers were about half the next 2 lowest TEs, and both of those teams (NYG and Pitt) have multiple 1000 yard receivers.
In conclusion, we need another receiving target who can put up 900-1000. Without it, we will not be a top 10 passing offense.
