As Andrew Scherber pointed out in his Breakout Wideouts article here on the Cafe, Ferguson--though technically in his fourth season--is really going into his third season of playing since he only played in one game his rookie year. I agree with Andrew that he's a good sleeper pick.
Likewise, although Lelie and Stallworth probably aren't available to you, you might consider Deion Branch if he's available but didn't make your list.
For 'safe' picks you have Bruce and Driver, both of whom will produce until they hang up their gear. Rice is still capable but I think he's used more as a diversion and threat, so I'm not sure if he gets the serious looks that Bruce and Driver will.
Antonio Bryant is another player who could come into his own this year. I wouldn't want to have to start him, but I wouldn't squirm if he was on my roster.
I think the Any Given Sunday philosophy can be extended to Any Given Season and that any of these guys 'could' perform. But some are on the way up, some are on the way back, and some are slipping off the radar. I shouldn't have to tell you which kind of guys you want to draft
