In fact, Texas coach Mack Brown was quick to point out Monday that Diggs — especially with his physical play — reminds him quite a bit of his older brother, former Longhorn standout and current San Diego Chargers cornerback Quentin Jammer.
"It's a family thing," Diggs said of his physicality. "It's something I've grown up with, having to go out and be physical. If your brother is going to be someone physical, you've got to follow him and be physical too. It's something I've been doing my whole life. Coach [Duane] Akina loves physical corners, so you've got to be physical to play in the secondary."
At the same time, Diggs admits that having a successful older brother has other perks.
"I talk to him everyday," Diggs said. "We have 5-10 minute conversations. We always talk. It's something that we've grown up doing. I always call and ask him for advice.
"A lot of conversations we have aren't even about football," Diggs said. "Only when I ask about something is when he'll tell me. But he watches all the games. He critiques some things that I do. We have competitions on who had the most interceptions. But it's nothing serious."
Diggs has emerged in recent weeks as more than just a physical cornerback. Against Texas A&M, he ran back a punt 81 yards that helped Texas take momentum and ultimately propelled the Longhorns into the lead. But Diggs said that his teammates were quick to joke about the fact that he was caught at the end.
"You're going to always get that," Diggs said. "But they understood what was going on. I made a great play because I had great blocking. So I was able to make the play. It should've been a touchdown, but we got the momentum going. That's all that mattered."
What is Diggs' ceiling? Brown said that some people already started tossing around comparisons to another great defensive back, one that he's not related to, in LSU star Tyrann Matthieu. As for Diggs, he's just focused on the task at hand, which includes trying to corral Baylor quarterback Robert Griffin III.
"It's really fun," Diggs said. "He's someone that is in the Heisman race. Someone that you're going to be watching in the NFL next year. So you go out and try to have your best game against someone like him."
