Brooks said he thought all three moved the ball well.
"I thought all three of them did some good things, and did some things they can't do, that we need to get better at," he said.
Hartline started the scrimmage with the first team and went 12-for-19 for 175 yards and no interceptions, although he did fumble the ball away once.
Hartline, who backed up Andre Woodson last year, thought he showed coaches what they wanted to see.
"I think the coaches see I can control the game, I can run the offense and I can move the football," Hartline said. "You come out and you try to perform well in front of the fans and your friends, but in the end it only matters what the coaches think.
"I think they realize I can play, I can come out where I can make things happen.
Curtis is a great runner, so he can come out and do things differently than I can."
Pulley was just 3-for-10 for 31 yards, but ran six times for 45 yards and directed three scoring drives, two touchdowns and a field goal.
"I think all our quarterbacks did pretty good. We moved the ball against the defense, which isn't easy to do because we're going to have a good defense," Pulley said.
Pulley threw one of UK's two interceptions when his bomb to Kyrus Lanxter fell short and Marcus McClinton intercepted it near the goal line.
"I see Kyrus behind the defense, and I just didn't get enough on it," Pulley said. "But Marcus made a good play, too. That was a good interception by him."
Fidler threw the only touchdown of the scrimmage, a 52 - yard bomb to Adams. He was 4 - for - 10 for 92 yards and also had a pass tipped at the line and intercepted by linebacker Micah Johnson.
Offensive coordinator Joker Phillips thought Fidler performed well when he was thrown in with the first team.
"He threw the ball really well today. And we actually put him with the (first team) to see what he could do, and he did a good job of moving the football for us," Phillips said.
Kentucky scored three times on the ground. Alfonso Smith got the first score of the game on a 5 - yard run around left end on a sweep.
Smith ran the ball nine times for a 60 yards with two touchdowns, but it was the running of sophomore Moncell Allen, who had 42 yards on seven rushes along with one catch for 19 yards, that Brooks was really pleased with.
"We lost one of the best backs in Kentucky history (Rafael Little), but we've got four (tailbacks) that can go in and do damage. And Moncell is just a load, he's so hard to tackle," Brooks said of the 5-7, 225-pound Allen.
"I was giving Sam Maxwell a hard time about missing a tackle in the backfield, and he said, 'He doesn't have any legs.' That's why you have to keep your feet moving and wrap up when you tackle him.
"But all four of those guys are capable of doing some really good things."
Derrick Locke had 31 yards on five carries and Tony Dixon carried five times for 25 yards. Fullback John Conner ran for 39 yards, and had a 35-yard touchdown run up the middle.
Room for improvement
The first - team defense allowed just two field goals in six series. The results were OK, but nowhere near where they needed to be, linebacker Braxton Kelly said.
"I thought we played pretty well, but we've got a lot of room to improve, assignment - wise and better tackling," he said.
"As a defense, we think we can be a little ahead of the offense right now. We have a little more experience, so we should be a step ahead of them and should have performed better than we did.
"We were looking more like we're reacting more than attacking."
Chris Cessna helped get the defense's first turnover when he sacked Fidler and forced a fumble that Luke McDermott recovered.
McClinton had his interception, and laid a big hit on tight end T.C. Drake when Drake went up high on a Fidler pass and took a shot in the gut from McClinton.
"I think we showed some good things on both sides of the ball," McClinton said. "We've got a lot of improving to do, but today was a good day for the first scrimmage.
