I'd go with this ranking in dynasty...
Stephen Williams - I was very impressed with this kid in the preseason. I can see him making an impact this year, in fact possibly this week, with Doucet out. His 6'5 frame is ideal for Derek Anderson, who seems to have better accuracy on plays up the middle where he can put some zip on the ball. It's the touch plays and floaters that elude him. Williams can be a sideline guy, but he did a lot of damage over the middle in the PS.
Sammie Stroughter - A guy who can play any position (flanker, slot, split end), plus I like his opportunity. He will likley be the WR2 for TB this year and with Josh Freeman running the show, he'll get lots of looks.
Brian Robiske - I do think he has the tools to do well in the league, but I'm not sure if Jake Delhomme or any Browns QB will be good for him. Their offense, just doesn't flow with the passing game. They are run-first team right now that often uses two TE sets. It limits the plays to Robiske, which in turn lowers his expected value for consistent production.
D.Jarrett - Jarrrett is only 23 years old and yet this is his 4th year in the league. I do think he has the skills to be a good down field receiver. His blocking has improved and it is resulting in him getting more looks. He had two catches last week (both on the same drive even). His size and leaping ability could land him as the WR2 this year. I do think he will beat out Brandon LaFell. As for extended value - it's hard to say, because the Panthers may be a completely different coached team in 2011 if John Fox is let go.
Steve Johnson - Until the Bills get a better QB, Johnson will be limited as far as what he can do. I do like what Chan Gailey has done so far with him. His size makes him a good red zone target. If the QB position improves or if he signs with a new team, I can see him having more success.
Riley Cooper - I don't necessarily love his situation in Philadelphia, but if something happens to Jason Avant, I can see Cooper getting some good playing time. It's hard to get a read on him, because he wasn't in a pro-style offense at Florida. I think he'll take some time to develop, but he does have promise.
Ramses Barden - Another tall WR with promise and potential. He has a lot of people ahead of him on the depth chart though, which makes it difficult to showcase his skills in games that count. He may be phased out or he may find a niche. Hard to tell at this point. If he does see the field, he has a good opportunity to make an impact.
DHB - I think he has bust written all over him. He has had opportunities to grow and develop and just hasn't yet.
