Even as the Dolphins continue working toward acquiring not one but two quarterbacks before April is out, Daunte Culpepper's days with the team have become numbered, according to those within the organization with knowledge of the situation. The Dolphins are still trying to acquire Trent Green from Kansas City, and although there is no timetable for that to happen, it is likely some movement will happen by the April 28-29 draft. The Dolphins also hope to pick a quarterback in that draft, with general manager Randy Mueller saying Sunday he believes the 2007 quarterback draft class is, ''a good group,'' and that ``five or six guys are first-day worthy.''
