Coston finished his career with 41 consecutive starts and helped clear the way for a rushing attack that averaged 4.5 yards per carry during his time in the lineup.
"He's a real, good young prospect," said offensive line coach Larry Beightol. "He is athletic. He's an explosive guy. He's tough. He's smart and he's hard-nosed. He's been versatile.
"We're going to have to see how much he can absorb and how far he can come."
Hawkins, In his only year of collegiate football (2002), saw action in five games for the University of Oklahoma Sooners as a true freshman. He recorded five tackles, a pass defensed and an interception, which he returned 45 yards for a touchdown.
Hawkins did not live with his parents in high school. He was raised by his high school football coach and only lasted one season at Oklahoma before quitting, despite his high accolades coming out of high school.
"He was the number-one defensive back (college) prospect to come out of the state of Texas," said Packers defensive coordinator Jim Bates. "He was one of the most heralded athletes. ... He came up here for the top 20 as far as the 20 (prospects) we had in (to visit this off-season). One mature young man. He has seen more in life than any of us."
He made an impression on the Arena Football League's Dallas Desperados coaching staff at the team's 2004 open tryouts. As a result, Hawkins had a chance to make his professional football debut in the AFL after signing with Dallas on Dec. 30, 2003.
He is a raw cornerback that displays the potential to be a solid professional football player and will continue to develop.
"He understands his mistakes in the past," said Packers scout Alonzo Highsmith. "It wasn't mistakes from alcohol or anything, he didn't know what to do in college. I don't know what I would do or what you would do in that situation. This kid is one of the finest athleties that I've ever worked out. He's fast. He's tall. He's a 4.3 (40-yard dash0 kid. It's a shot in the dark to take this kid. It's a gamble, but the return can be so great."
