It will be interesting to see how Devard Darling plays Friday night against the Vikings. He has a habit of having strong preseason games, or several spectacular catches, and then he disappears. He certainly has the tools. He's not super fast, but has decent speed. He's got good size, and certainly has good hands. But just like Clarence Moore, he can disappear from an offense and drop easy passes that hit him in his hands. It's a good matchup with him and rookie Demetrius Williams competing for the No. 3 receiver spot. Williams gives the Ravens what they desperately need, a constant vertical threat. But he lacks experience, and like most rookies, will probably tire down the backstretch of the season.
