Free-agent signing Louis Delmas is coming off a lackluster season with the Detroit Lions, but he can still be an impact player in this league. Although the Dolphins don't have a pressing need at the position, I do think they'll bring in some competition sometime in the second half of the draft. An interesting player to keep an eye on is USC's Dion Bailey, who probably will be available in the fifth or sixth round. He picked off five passes last season at safety, after playing linebacker during the previous two years. With Bailey's versatility, I expect him to be an outstanding special teams player at the next level.
