BEREA, Ohio -- Thursday's training camp session gave Browns fans a glimpse at just how special this offense can be. When Baker Mayfield is connecting with Jarvis Landry, Rashard Higgins, and Odell Beckham Jr., the group has a feeling of invincibility.

You can see the look the players get on their faces. The body language changes, the atmosphere lifts, and the entire offense is raised.

Mayfield hit Beckham on a dig route in an 11-on-11 session, and the group looked unstoppable. It has that vibe. Then, on the next snap, right guard Austin Corbett let his man cross his face and the pressure forced Mayfield into a poor throw.

The reminder was there once again.

No matter how much skill position talent the Browns have, they will be relying heavily on this offensive line to give Mayfield the time to throw to open receivers who are some of the NFL's best weapons.

NO CLEAR LEADER

The right guard rotation has been taking place since minicamp. Austin Corbett works with the first team one day, Eric Kush the next, then Kyle Kalis on the third day.

The team wants one of the linemen to stand out and earn that job. That has yet to be the case.

Kitchens was asked about the status of the right guard job earlier in the week, specifically if he noticed anyone gaining an advantage. "No. There is not.” He then continued.

“I wish one was, but I want them all three to compete. They have all had some good plays. They have all had some bad plays. Under no circumstances are we ready to name the starting guard.”

WHO WINS THE JOB

The outlook remains uncertain. All three players have shown quality reps, but with too many mistakes.

Joel Bitonio says all three have the ability.

"They just want the best guy there, and they feel like there are a few guys who have the ability to start at that position," he said, "so they are going to try and work it and put the best guy there and make them earn it."

Opportunity is there every day. The issue is the lack of consistency.

Playing offensive line in the NFL is about consistency. The more you can avoid mistakes and allow your running backs and quarterback to do their jobs, the better you are. The Browns need the one player who can avoid those mistakes.

SCOUTING REPORTS

Although it's a challenge to get a feel for the three players from the sideline, watching drill work and 1-on-1s can allow for some insights into what the player can be, and where they struggle or thrive.

Corbett plays with a strong base and athleticism, but he lacks the consistency in his punch and ability to steer opposing linemen -- an essential skill whether it's helping form the pocket, or handle angles in the run game.

Kush seems to have the ability, but his mental makeup comes with question marks. Several times during camp Kitchens has had to yell at him about mental mistakes, including penalties and missed assignments. Those things linger in a coach's mind.

Kalis is likely the strongest of the three players but his balance is an issue. Too often he lunges or takes the incorrect angle and it forces his feet to catch up before they should. When defenders have been able to make him work off his strong base, he doesn't have the lateral agility to get where he needs to go.

FINAL THOUGHTS

In all likelihood Corbett remains the front-runner. He has been the most consistent of three, and his position with the franchise has the most invested.

Veterans like Bitonio know there is still plenty of time, however.

"Greg (Robinson) kind of took it over and proved that in eight games last year that he could be a left tackle when he is motivated, thinking and doing the right things," Bitonio said. "That is kind of where we are at in that situation.”

Mayfield echoed the same sentiment.

"Greg (Robinson) did not play until whatever week it was last year," said the QB. "We just want to have consistency, being on the same page. ... Whatever guy is going to be the most physical and get his job done and be the best fit for us up front is going to win that job. We have a great offensive line coach (James Campen), and we are grinding right now. We are trusting that competition will work itself out.”

This situation will be solved in the preseason. The winner will get in-game opportunities with varying schemes and challenges.

The Browns made it work with a questionable offensive line in 2018. They will be looking to do the same again at right guard. Time is on their side, but the pressure is still there.

Kitchens and James Campen know they have to get this decision right.
