Clayton was a late addition to Senior Bowl week and impressed scouts with his speed and ability to get to the second level on his runs, but his ability to catch passes out of the backfield is questionable, according to Scout.com.
During the Kansas State pro day on March 26, Clayton (5-foot-9 7/8, 211 pounds) ran the 40 in 4.58 seconds with the wind and 4.65 against the wind, according to NFL.com. He also ran the short shuttle in 4.42 and the three-cone drill in 7.28. In addition, he had a 36-inch vertical jump and a 10-foot-2 broad jump.
The powerfully built Florida State University transfer is expected to be a late-round draft pick, despite missing the last half of the 2006 season with a knee injury that he sustained in a practice.
Clayton played in five games, rushed 67 times for 338 yards (4.8 avg), third on the team, and three touchdowns. He also caught nine passes for 45 yards.
Leon Patton led Kansas State in rushing with 640 yards on 108 attempts (5.6 avg. per carry) last season.
The Packers lost Ahman Green to free agency this season and are expected to build depth at the running back position. Many draft experts feel the Packers will select Marshawn Lynch with their first overall pick, but look for Green Bay to select another running back in a latter round, or sign one as a free agent at the conclusion of the draft, to improve the competition among the backups. San Francisco is looking to find a solid backup for starter Frank Gore.
Each NFL team is allowed up to 30 pre-draft visits. The Packers also have met in Green Bay with Lynch, UNLV cornerback Eric Wright and University of Pittsburgh linebacker Clint Session in recent weeks.
