The Raiders' brass returned from the NFL Scouting Combine less convinced that Louisiana State QB JaMarcus Russell is their man for the top pick and with more questions than before after taking a long look at him during the process. Publicly, the Raiders said nothing about Russell or any of the other players who attended the Combine. Privately, several Raider officials questioned Russell's work ethic, said they are concerned about his weight as a long-term issue, and cautioned against making Russell a cinch as the top pick. It now appears just as likely that the Raiders will target Georgia Tech WR Calvin Johnson in light of his posting a 4.31-second 40-yard dash, as well as a very impressive interview.
