The Bears sent their second (63rd overall) and fourth (129) round selections to Dallas in exchange for the Cowboys third (72), fourth (104) and fifth (140) picks.
The Bears used the 72nd choice to boost the secondary. Chicago selected Tuskegee University cornerback Roosevelt Williams.
The 5-11, 202-pounder attended Division II Savannah State College where he started and returned kickoffs in 1998 and '99.
In 2000 he transferred to Division II Tuskegee, where he registered 32 tackles, four interceptions and 23 pass breakups as a junior. Opposing offenses shied away from him last season when he recorded 14 tackles, five interceptions and 12 breakups.
Williams was also a contributor on special teams, recovering a blocked punt for a touchdown and returning two kickoffs for 77 yards last season. As a junior, he returned nine kickoffs for 155 yards.
Bears GM Jerry Angelo said Williams should make an impact on special teams.
"The nice thing about taking a big corner he should be a good teams player," Angelo said. "Versus a little corner you get a little bit nervous about sending them down (on kick coverage). So, that played a little bit into our thinking too. He should be a good team player either as a returner, which he's done and did well at that level, and obviously as a cover person."
Williams added he doesn't mind earning his stripes on special teams.
"I did a little bit of special teams in college," Williams said. "I did what I had to do to help out the team and it would not be a problem if I played special teams in the NFL."
In the trade with the Cowboys the Bears moved from the 31st pick in the fourth round to the sixth. Two need areas the Bears might address early in day two are quarterback or pass rusher. Both Alex Brown out of Florida and Kurt Kittner from Illinois are still available.
If the Bears chose to go with Brown Chicago could use one of its two fifth round choices on a quarterback. There is a strong possibility LSU's Rohan Davey could still be on the board.
