Play of the Day: Hamlin closes

SAN ANTONIO -- Michael Hamlin has to make up a lot of ground on Alan Ball to force the coaches to make a difficult decision when selecting the starter at free safety.

Hamlin showed during 7-on-7 drills that he can close quickly.

Roy Williams beat Orlando Scandrick with a double-move and appeared to be wide open down the left sideline when Tony Romo released the ball. However, Hamlin prevented Williams from having a chance to make a big play, sprinting from the middle of the field to break up the pass.

It was a sample of Hamlin's playmaking ability, which is the primary reason the 2009 fifth-round pick might challenge Ball.

"We're not giving anything to anybody," Phillips said. "They have to earn it."
