Missouri quarterback Blaine Gabbert worked out for a number of coaches and executives, including Denver's John Elway, at the school's pro day last week. The crowd included Elway and Broncos coach John Fox, Jets coach Rex Ryan, Jim Harbaugh of the 49ers, Bengals coach Marvin Lewis, Leslie Frazier of the Vikings and Tennessee coach Mike Munchak. The Panthers, who have the draft's top choice, sent several representatives.
