It was hot afternoon for Day 4 of training camp as the Browns continue to install their playbook on both sides of the ball.

"I wish we could go another couple hours, but I don't know if our guys could stay out here in this heat," head coach Hue Jackson said, laughing. "It was another day for us, wasn't as sharp as I'd like for us to be, but again, that's kind of to be expected when you go after it hard."

The Browns put on full pads Sunday for the first time since January and held a feisty practice that featured two live tackling sessions.

"I like the energy of our football team, I like that they come back out here in the middle of a lot of installations offensively and defensively and special teams but I think they've handled it well," he said.

"And again, I give a lot of credit to our veteran players because I think they understand the process and so they're trying to bring the young guys along each and every day. We're just going to keep stacking up good days and put our heads down and keep grinding and be a gritty group."

Without further ado, here's five things to know from Monday's practice

Full pads, full go

Jackson outlined why the Browns will most likely keep wearing full pads for the rest training camp.

"I think it's important that the guys get in football pad shape — whatever you want to call it, if you can call it that — because I think it's important how you wear your pads and how you play in your pads is obviously how you play the game," he said.

"At some point in time, we'll back off of that, but we're gonna wear them in training camp because I think that's what's needed."

Hughes ready for bigger role

Fifth-year defensive lineman John Hughes said he's prepared to play a bigger role on a defensive line looking for ways to replace the production of veteran defensive end Desmond Bryant, who will miss the season after having pectoral surgery earlier this month.

"I waited my turn for a long time, played behind a lot of great D-linemen and learned a lot," he said Monday, "so I think it's my time."

Hughes, who has made 10 starts in four seasons, said he knows he'll have to earn that right.

"I come in with the mentality to compete. We're all competitors, that's why we're all out here," he said. "That's why we all made it to this level, so just come out here and compete and have fun."

Kirksey's ready for anything

On Sunday, Hue Jackson called defensive coordinator Ray Horton a "mad scientist" when it comes to creating different schemes for the Browns defense. One such player who could have a varied role in those formations is inside linebacker Christian Kirksey.

"I could see him using me in whatever way he needs me to do. Right now, I'm grasping the playbook to a T, just running around in camp trying to figure out where my strong point is going to be," he said. "We'll see where it takes me."

Kirksey is expected to play a big role on the Browns defense — especially in stuffing opposing run games — along with middle linebacker Demario Davis.

Pryor impressed by rookie WRs**

After an offseason of growth and development, Terrelle Pryor could potentially play a key role on the Browns offense this season.

But the former Ohio State star welcomes competition, saying Cleveland's rookie wide receivers have impressed him thus far.

"They're all hungry, that's all you can ask for. If you look at a guy and if you draft a guy — if I was like an owner or a coach — I'd want to see what's this guy's attitude, does he always want to get better, is he always on the field after practice, is he always on the field early, is he attentive and talking and asking questions in meetings, is he surrounding himself, working with DBs and the older receivers and these guys are like that," Pryor said Monday.

"Corey Coleman, he's going to be very good. He's a very hard worker. All these guys are very hard working, they all have the same itch. It's going to be fun to see those guys play."

Connor Hamlett learning from Barnidge as he vies to be No. 2 TE

Seven months ago, Connor Hamlett was signed to the Browns practice squad. Now, the first-year player from Oregon State has emerged as a potential candidate to be the team's No. 2 tight end behind Pro Bowler Gary Barnidge.

"I'm just trying to do my job and do anything I can to help the team."

The 6-foot-7 Hamlett stood out during offseason workouts and has continued his strong play in training camp. "I think the ability to stretch the field. With how big I am, (I'm) just a big catch radius," he said. "Mismatch potential. Things like that."

Hamlett added he's sought out the advice of the veteran Barnidge as training camp continues

"He helps all of us out. I think he might know something, but he'll add the little detail that you need to know, the adjustment you need to make on the run," he said. "I'm not going to ever say I got it because he has all the experience and he's willing to help all of us out."
