The Cleveland Browns open training camp on July 27 at the team's facility in Berea, Ohio. Here’s a closer look at the Browns' camp:

Top storyline: The usual quarterback drama persists, but the Browns have put a lot of energy and focus on the defensive side of the ball this offseason. They are putting a lot of belief in the arrival of coordinator Gregg Williams, whose loud and in-your-face approach is a complete contrast to the cerebral approach of Ray Horton a year ago. Style aside, Williams' attacking style has believers in personalities as diverse as Aaron Donald and Scott Fujita. The Browns added two defensive tackles (Larry Ogunjobi and Caleb Brantley) in the draft along with end Myles Garrett, the first overall pick. They signed a third corner (Jason McCourty), whom Williams previously coached in Tennessee. They feel that Jamar Taylor, Danny Shelton, Chris Kirksey and Emmanuel Ogbah are talented returners. It's clear that the Browns hope to win with defense, and they've entrusted that side of the ball to Williams, who will not be shy about his approach or his feelings.

QB depth chart: Uncertainty reigns -- again. Cody Kessler figures to start camp as the No. 1, but Brock Osweiler and DeShone Kizer will be given chances to win the job. Odds favor Kessler, who started eight games a year ago. But Kessler had two concussions and bruised ribs, so he needs to stay healthy through camp. He also needs to perform better on the field than he did in offseason work, in which Osweiler was a pleasant surprise. Kizer has immense talent, but when minicamp ended, both Kizer and coach Hue Jackson said that Kizer was not yet ready to start a game. Whether he can be by the end of preseason will be one of the more watched and interesting stories of camp.

Bubble watch: Defensive lineman Desmond Bryant was a productive player for the Browns, but he missed all of the 2016 season after he tore a pectoral muscle while working out on his own in the offseason. He now has to show he's healthy and prove himself to a new staff. Jackson coached Bryant in Oakland, and Bryant has become the elder statesman of the defensive line group. But there are several young linemen the Browns have drafted the past couple years who could push Bryant out of a job.

That rookie could start: Tight end David Njoku was noticeable the first time he stepped on the field in rookie minicamp. He's a big target who looks strong and far more polished than a 20-year-old should look. The biggest question for Njoku is whether he can take the pounding of an NFL tight end. That isn't something he has had to deal with. But in terms of hands, size, the ability to go up and get a ball, and potential, Njoku brings a lot to the field.

Receiving issue: The Browns have to find receivers from somewhere, as the group consists of Kenny Britt, Corey Coleman and a bunch of guys who haven't played much. Coleman had a rookie season that almost had him apologizing when it ended; he has to come through. But so does at least one of the other rookies drafted a year ago. The one guy who stood out in minicamp with his attitude: Ricardo Louis. As a rookie, there was buzz behind the scenes that Louis would and could be a good player once he got the NFL approach. He seemed much more comfortable in minicamp, and if that translates to games, he could well seize the third receiver's job and push for the second. If he does, it would be a dream come true for the offense.

First-round dues: This is an important time for two first-round draft picks. Coach Hue Jackson pointedly challenged Coleman in the offseason, saying it was time for Coleman to step up, grow up and move past the excuses of playing in a more complex offense (compared with Baylor's) and adjusting to cold weather. Coleman needs to produce. Cam Erving, meanwhile, might be looking at his last chance to stay in Cleveland as he moves to right tackle. Jackson said that the Browns would put him out there and see what he can do. If Erving doesn't show he can play there, he might not be with the team in September.
