"I thought it was awesome," Brewer said. "The Opening was great. You had the best athletes and the most speed I've seen at any camp or combine. It was definitely eye opening, and was probably the highest level of play I'll take part in until I go off to college.
"Getting to play with the best talent from throughout the country, I could see that I still had stuff I need to work on," Brewer said. "I can't wait too long to throw the football. I need to work on that."
The Opening also gave Brewer a chance to mesh more with his future Longhorn teammates.
"Besides my high school team, this is the closest group of guys I've been around," Brewer said. "I think they're a great group of guys, and the bond that we have together is something that you get when you have the kinds of people that Coach (Mack) Brown recruits.
"People look at us, and I think you saw that with Nelson (Agholor) and Torshiro (Davis) … I think it definitely impressed them," Brewer said.
Brewer said Agholor spent quite a bit of time with the Longhorn contingent, and added that Davis wound up eating with the group near the end of the camp.
But whatever happened off the field, Brewer said he really enjoyed what happened on it.
"I threw routes to Cayleb (Jones), played against Peter (Jinkens) and Tim (Cole) and played with Johnathan (Gray)," Brewer said. "It was great to see what it was like in a competitive setting with them, and everybody played really well."
That includes DeSoto cornerback Bryson Echols, who caught Brewer's eye when they played against each other.
"He screwed my timing up some," Brewer said, laughing. "He's a good cover corner. A couple of times I looked to his side and he messed up my vision by re-routing our guy."
Brewer's timing was rarely off with Gray, who spent the weekend acting as Brewer's running back. The duo established such a chemistry that Gray made the all-tournament team.
"In 7-on-7, it definitely helps if you have a good running back," Brewer said. "He's the guy you look to when things break down in pass coverage. Knowing that (Gray) is going to be 1-on-1 with a linebacker, that's a matchup that he's going to win. I threw to him a bunch, and he did a really good job."
Brewer has a packed summer schedule still awaiting. He was selected for the prestigious Elite 11 camp next week, and is trying to clear his schedule to accompany star recruit Andrus Peat to Austin on July 25 and 26.
If he can't make that trip, it won't be long until he next visits the 40 Acres. Brewer said he'll make it to at least one game this fall, and he still plans to graduate early and enroll at Texas next spring.
