Terrel Owens and Lee Evans, even with a struggling quarterback, are two dangerous receivers.
I don't think you need to see the credentials, so you can take my word for it that T.O. has been a dangerous receiver for a long time in the NFL.
Both can threaten deep and both can stretch the field with YAC (yards after catch). Bills tight ends Shawn Nelson and Derek Fine have been almost invisible this year in the passing game.
The problem that continues to plague Miami is receiver. They have not found a number one receiver, and Ted Ginn continues to struggle in the passing game.
Davone Bess, Greg Camarillo, and Brian Hartline have been good this year, but they still don't give great ability to stretch the field.
Anthony Fasano has done nothing this year and is now injured and Joey Haynos has shown promise but hasn't fully been the answer at tight end.
Watch out for a guy named Kory Sperry, though. He has shown good potential so far.
