I for the most part agree with you, however:
Most other teams have better weapons, whether it be a RB coming out in the flat, a pass catching TE, or a bigger Wideout. Josh Reed is definitely dangerous, but let's remember why Jim Kelly was so successful. HE GAVE THE RECIEVERS A CHANCE TO MAKE A PLAY.
He would throw the ball in the air with the confidence that either Reed, Thomas, Lofton, Metzalaars, or Beebe or somebody would bring it down. This also made the running game so effective, defenses knew that Kelly was going to go over the top and they were scared to death of it. I'm not saying Trent Edwards can't do that, but you gotta have balls. Jim Kelly had it and that's why Jay Cutler has had a lot of success (with the exception of last week, however he did throw for over 360 yards) he's got a set on him.
Bottom line: Lee Evans is a number one receiver, but we need to throw the ball up more and take chances or get another weapon or two. Hardy hasn't worked out so far, but Steve Johnson looks good and we need a TE. I'm optomistic.
