Michigan receiver Mario Manningham, whose draft stock has taken a huge hit of late due to a reputation for the dropsies, slow (relatively speaking) times in the 40-yard dash, alleged misrepresentations in his Scouting Combine interview regarding past marijuana use, and most recently a train wreck of an interview with Sirius NFL Radio, is scheduled to visit with the Oakland Raiders, according to David White of the San Francisco Chronicle.

But with the Raiders picking first at No. 4 and next at No. 104, Manningham would have to plummet all the way into round four before the Raiders would get a shot at him.

Unless, of course, the Raiders are plotting a possible trade down, and eyeballing prospects who might be available with some of the lower picks that they pick up.

We recently reported that the Raiders also will be meeting with Michigan State receiver Devin Thomas, who likely will be available in the second half of round one.
