Brown spoke briefly about the difficulty of his decision.
“It was very difficult under the circumstances,” Brown said, “but it was the decision that was best for me and my family. There's no disrespect to Penn State and the players.
“They're still part of my family. I still talk to them every day. I'm trying to get to know a new family now.”
Stoops said he is already impressed with the 6-foot-3, 210-pound Brown's hands, speed, intelligence and punt returning skills, adding that he'd “absolutely” return punts for OU in 2012.
“With a big, strong guy like that punt return-wise, he can run through those tackles or people trying to grab his jersey and pull him down, that's not going to happen,” Stoops said. “He catches (punts) as easily and smooth as anybody I've ever seen.”
The Sooners' offensive system is obviously new to Brown, and he'll have to learn fast; OU's season opener, Sept. 1 at UTEP, is less than a month away.
“Won't take him long,” Stoops said. “In one day out there, he's standing with coach (Jay) Norvell and I, and he's already mouthing the signals. It won't be but a couple, three days and he'll have 90 percent of it.”
Because of NCAA rules, Brown is practicing in just a T-shirt and shorts, unlike his Oklahoma teammates, who are in shoulder pads. He'll get to put pads on for OU's second Wednesday practice, Stoops said.
“Looking out there today, and you see him added to the equation,” Stoops said. “A guy that's a senior that has three years experience of playing and fighting people, crack-back blocking on people, catching the ball. ... It's going to be exciting.”
