Even so, Brown left the four contenders to start at the position with a simple directive during the summer months: improve even more.
"I really wanted to see from the end of April from the spring game until when we started on Monday, was how much (more) they improved fundamentally because I gave them a lot of different things to work on," Brown said.
A week into fall camp, no decision has been made at quarterback. What is clear, however, is that Patrick Towles, Reese Phillips, Drew Barker and Maxwell Smith completed their offseason assignment.
"The guys have really done a nice job," Stoops said at Media Day. "They're better rounded, and I expect them to go out and play well. I think we have good competition there. They're all doing some good things. They're not perfect, but they're much improved."
Towles, to start with, has continued to speed his release, according to Brown. A combination of mental and fundamental work has been the driving force behind that.
"With making decisions, that comes from just understanding the offense," Towles said. "You know the offense better, you know when people are going to come open, you know where people are at. So then it's easier to get the ball out. And then fundamentally, last year my release was too long, so even if I made a quick decision it still might have taken a little bit for the ball to get there. Now my release is quicker and I have a better understanding of the offense to where I'm on time all the time."
Phillips, praised repeatedly as the most consistent quarterback of the bunch, has upped his arm strength. Like Towles, that's due in large part to a team-wide focus on fundamentals.
"My drops have become a lot faster," Phillips said. "With that, I can use my legs more. I don't have to rely on just using my arm."
Along those same lines, Barker has cut down on the mistakes that plagued him in the spring, when he arrived a semester early after graduating high school in December. Even though Barker reported he led the quarterbacks in touchdown passes during spring practice, he also threw the most interceptions.
"In the spring, I was learning something in the meeting room 15, 20 minutes before practice and then I would go out and have to do it against a live SEC defense," Barker said. "Sometimes, to be honest, I wouldn't know what I was doing. This summer, I really sat down and studied the playbook; tried to learn more about defense, coverages, blitzes, stuff like that; and just make better reads and be more confident in my decisions."
Smith, practicing fully every other day, has been more effective throwing the ball over the middle of the field.
"My mindset is just to come out every single day, work as hard as I can, do everything the coaches ask, help the guys around me, not just these quarterbacks, but everybody else, making sure they know what they're doing and make our team as good as we can be," Smith said.
Though Smith -- the veteran of the group -- is committed to helping his team, don't mistake that for a concession. He's out to win this ongoing battle.
"If I didn't have my eyes on the job, I might as well just call it quits now, in my opinion," Smith said. "Of course I've got my eyes on the job. I'm not the kind of person that's just going to lay down and just hand it over, like 'you guys can take it now.' That's not me. That's not who I am."
Smith is wise not to give in because Stoops says the competition remains "wide open," though that figures to change quickly.
Over the first days of practice, coaches avoided turning the intensity in practice up to the highest level due to a study by High Performance coach Erik Korem that revealed more injuries occurring during finals week. With summer classes now over, that will change with a practice on Friday afternoon and two more on Saturday.
"Now we're going to pick up starting this afternoon and do a lot of good on goods, throw our quarterbacks in a lot of different situations," Brown said. "I hope within the next five or seven days, one of those guys (is) going to stand out."
Each of the four quarterbacks hopes to be the one, but they know getting caught up in that will do them no good.
"Every week is a big week," Towles said. "The spring was the biggest spring of my life. Each practice, the next practice is the most important practice. Each play, the next play is the most important play. So I really can't think about two days from now. I gotta think about today. We've got practice at 3. I'm just worried about that."
Brown has done everything in his power to give the quarterbacks plenty to worry about in practice.
"In the spring, I took this approach," Brown said. "We're going to have fun. We're going to enjoy this. Focus on getting better, you individually getting better. ... Now I'm telling them, hey, we're looking for a guy to win the job. Go win the job. Everything that you do during the course of a practice is getting judged. Yeah, you'd better have fun with it, but understand we are keeping score."
With more third-down work, lots of talk and harder coaching, Brown is trying to simulate the pressure whoever wins the job will face on game day.
"I think it's just the intensity from Coach Brown is a lot higher now than it has ever been," Phillips said. "He's an intense person, but at the same time he kind of knows how to keep us relaxed. Now he's not doing that. He's trying to get in our heads. When we do blitz or team, he tries to put in situations to where it's going to be hard and we have to overcome stuff."
Clearly, Brown has no intention of making it to the season opener on Aug. 30 with no quarterback taking hold of the starting position like last season. Stoops, however, won't make a decision until it's appropriate, regardless what happened a year ago.
"Right now it's just too even," Stoops said. "I've said it before, it would be too reckless just to make a decision because I want to make a decision and not answer those questions. I'm not going to do that. It's not fair to the players. It's not fair to our team. It's not fair to the future of our program."
