The San Francisco 49ers have few holes to fill on their team. While some figured they were a lock to draft a wide receiver in the first round, the team signed numerous receivers in the offseason, including Randy Moss and Mario Manningham. GIven their sudden depth at the position, many draft experts started to believe they will look to improve on the defensive side of the ball.

USA Today recently surveyed five draft experts and asked them to project the first round of the 2012 NFL Draft. Four of the five picked a different player.

Staff writer Jarrett Bell has the 49ers taking defensive tackle Devon Still out of Penn State. Jim Corbett has the club going with Wisconsin guard Kevin Zeitler, while Nate Davis has them going with another Wisconsin player in center Peter Konz.

Rob Rang of NFLDraftScout.com also has San Francisco going with Zeitler. Wes Bunting of National Football Post has them taking Stanford tight end Coby Fleener, who played under head coach Jim Harbaugh in Palo Alto two seasons ago.

The first round of the draft is set for Thursday, April 26 from New York City.
