"It was tight," Tatum said, "but Coach (Mack Brown) didn't want me to run the 40."
The Fort Worth athlete has been nursing a hamstring injury back to health and believes he's finally healthy.
"I'm fine," Tatum said, "Coach just didn't want me to risk it. I did everything else...the pass coverage drills and they (Texas coaching staff) said they were impressed."
So you shut 'em down?
"Yeah, I shut 'em down."
The state's No. 2 corner prospect also got the opportunity to watch fellow Longhorn commitment Ryan Palmer.
"I think you ranked him too low," Tatum said. "He did good at the camp, I mean he did real good. He was better than I thought he would be."
About the only difference between himself and Palmer, Tatum said, "is the height."
"He may only be 5-8 or 5-9, but he can play!" Tatum said. "He shut down the 6-3/6-4 receivers...put a blanket on 'em. And he clocked a 4.33, I think."
Tatum said he's been kickin' it with Palmer and the two have become pretty good friends.
And the Dunbar prep also added that the Longhorns were really impressed with his little brother, Brandon Tatum, a junior-to-be.
"Texas was all over him," said Tatum, the nation's No. 86 overall prospect in the newly released National Hot 100. "He's taller than I am. He's 6-1, 190 pounds...he's a running back. But he can run a 4.45 and play DB too."
"Coach Haywood really liked him," Tatum said with a lot of pride. "Coach Tolle liked him. And Coach Akina liked him as a DB."
