The defensive backs are doing their drills today and Nebraska cornerback Prince Amukamara, who heard questions about his lack of speed, turned in 4.37 and a 4.44 in his 40-yard dash. These times are unofficial.
"The 40-yard dash is rated real high at the combine and I'm looking forward to doing real good at it," Amukamara said last week. "I know I'm going to run real well."
Several mock drafts have the Cowboys taking Amukamara with the ninth pick of the draft and team officials have already spoken to him.
It was interesting to note that Amukamara's senior season saw him with no interceptions in the pass-happy Big 12 and there were questions about his lack of speed hurting his playmaking ability.
"I think some people don't know what they're talking about and haven't seen me on film," Amukamara said. "I guess I'll show them on Tuesday."
Some other strong 40 times: Buster Skrine of Tennessee-Chattanooga ran a 4.29, LSU's Patrick Peterson ran a 4.32 and a 4.37, Ohio State's Chimdi Chekwe ran a 4.33. Colordao's Jimmy Smith ran a 4.38 on his first attempt. Texas' Aaron Williams ran a 4.53.
