In addition to spending four years playing baseball in the Boston Red Sox and Chicago White Sox organizations, Jenkins was a quarterback at South Carolina before playing strong safety the last two games of his senior season.
The Dolphins will use the 6-foot, 200-pound Jenkins as a weakside linebacker and on special teams.
Probably the most interesting pick of the fifth round was Tolver, who had a phenomenal 2002 season. Tolver, who compared himself to Steelers Pro Bowl wideout Hines Ward, caught 128 passes for 1,785 and 13 touchdowns.
He and teammate Kassim Osgood set an NCAA record for most combined catches in a season by two teammates.
Tolver is 6-1, 202 and, in the words of Dolphins senior vice president Rick Spielman, more of a possession receiver than a burner.
"He's not a great speed guy, but he made a lot big plays," Spielman said. "He's got very good quickness for a big receiver and he knows how to use his body to create separation."
As for Lee, he didn't put very big numbers at Mississippi State because the Bulldogs had serious problems at quarterback last season.
But Lee showed off his receiving ability when he earned MVP honors at the East-West Shrine Game.
"He was one of the highest-rated tight ends on our board," Spielman said. "It's almost like the same scenario at linebacker. He's a young guy who's going to come in and compete and see where we go from there."
