The longest sustained cheers during the second day of the draft have come for safety Caleb Campbell, chosen in the seventh round (218th overall) by the Detroit Lions.

Campbell played his college ball at Army, and he’s the highest-selected player from Army since 1947.

In the past, athletes from West Point were required to serve five years of active duty in the military before they could begin their professional careers, but military rules have changed, and cadets with the ability to play sports professionally are now allowed to do so while helping out with recruiting efforts for two years.

“I’m serving my country in a different way, but I am serving my country,” Campbell said on ESPN shortly after the Lions selected him.

If Campbell sticks in the NFL through his two-year recruiting requirement, he can then buy out his remaining three-year commitment by agreeing to six years of reserve time.
