Roby's legal issue could affect 49ers

Former Ohio State cornerback Bradley Roby was arrested over the weekend for OVI -- operating a motor vehicle while impaired -- in Ohio. He is considered a top NFL draft prospect and could be a target of the 49ers at pick No. 30.

However, because of all the off-field issues surrounding the team this offseason, it would create a major stir if the 49ers used an early pick on a player fresh off an arrest.

Roby’s problems could make it difficult for the 49ers to grab a cornerback at No. 30 because it lessens the potential options. There are a lot of teams looking for a cornerback in the first round. Along with Roby, the top cornerbacks available are Michigan State’s Darqueze Dennard, Oklahoma State’s Justin Gilbert, Virginia Tech’s Kyle Fuller and TCU’s Jason Verrett.

All four of those players could be taken before the 49ers choose.
