I don't see what all the commotion is, David Nelson was a high character guy with good work ethic, but when he was on the field, vanished for games at a time. He had a few very good games with some nice highlights, but in the end, that's simply not good enough to win in the NFL, plain and simple. If the new coaching staff fields mostly the same team as last year, do you really expect anything more than 7 wins? If you think a new starting QB puts this team in the playoffs, you are greatly mistaken.
There is far more average talent on this roster than there is elite talent, so the coaching staff is making some changes. This really isn't news, its just business when a new coaching staff comes in. There won't be a lot of interest in his services, much like Donald Jones, and every other receiver this team has cut in that last few years.
