Training camp should reveal some answers to lingering offensive line questions. (John Kuntz, cleveland.com)

CLEVELAND, Ohio -- It's a new era for the Browns' offensive line. Joe Thomas retired in March, leaving an enormous vacancy, one that they struggled to fill last season after Thomas got hurt.

The domino effect from that retirement will be felt this training camp. The Browns, like they did with many other positions, threw valuable resources at the position -- and even took a few flyers. Meanwhile, they hope that right tackle will stabilize with a key free agent addition.

I went in-depth at left tackle earlier this month, but here is a full preview of the team's tackle position.

Right tackle: Chris Hubbard

"I came here to play right tackle," Hubbard said during his introductory press conference in March.

After four seasons in Pittsburgh, Hubbard signed in Cleveland for five years and $37.5 million. Hubbard started 10 games for the Steelers last season and four the year before that.

Offensive line coach Bob Wylie acknowledged after June's minicamp that they did give Hubbard some reps at left tackle, but expect him to remain on the right side of the line throughout camp and into the regular season.

Left tackle: Shon Coleman

There's no question about Coleman's athleticism.

"He has the athleticism," Wylie said. "We need to keep working on the fundamentals. He's a good enough athlete that he gets himself in some awkward positions and gets himself out of them. He has to keep working on the footwork and the hands."

Coleman was up-and-down in 2017 at right tackle. Now he returns to a familiar side of the line -- he was a left tackle at Auburn -- and he gets the first crack at replacing Thomas.

Austin Corbett

The Browns have options with Corbett, and one of those options is left tackle. It's hard to believe that the plan for the No. 33 overall pick is to use him as a swing lineman on the interior.

"He's smart and that's why we gave him the workload we did at the different positions," Wylie said. "We're not concerned about him the player. We're just concerned about which one is his best spot."

Corbett played left tackle at Nevada, replacing current Browns left guard Joel Bitonio. He spent time working with the second team at left tackle in the spring.

It's also entirely possible that, if the Browns consider Bitonio at left tackle, Corbett could slide into Bitonio's left guard position. Corbett could also have a future at one of the other interior positions after this season.

Desmond Harrison

Proceed with caution in hitching your wagon to undrafted free agents who haven't proven it at the NFL level yet, but it's not meaningless when Wylie says something like this about a player:

"Desmond (is) probably the smoothest athlete we have. As a pure, smooth athlete doing it the way it should look with his feet and his hands, bending his knees, he's one of the smoothest we have."

Harrison really is about as big of an unknown as you can have and he's probably the biggest wild card in all of this. During some of the practices open to the media this spring, he worked higher up the depth chart.

"His thing is he has to do it mentally," Wylie said. "Has to learn to play like a pro. Physically he's fine. Now it's seeing the defense. Find your triggers. The last guy you need to see is the one you're gonna block. He doesn't know how to do that yet because he hasn't played, and the only way you're gonna get better at the sport, period, is to play."

The former No. 2 overall pick was signed last month. The Browns will be the 2014 draft pick's third team. He struggled filling in at left tackle for the Lions a season ago, so this is nothing more than a flyer on a player with a high draft pedigree.

Joel Bitonio

Don't Edit

Until a left tackle is named or we're just outright told that it's not happening, Bitonio should be included in any discussion of the position. The Browns seem hesitant to weaken left guard -- Bitonio is one of the league's better ones when healthy -- but if he can play left tackle at a similarly high level, they have other options at guard.

Wylie said that Bitonio took some reps at left tackle during the spring, but this still feels like more of a last resort. That said, the mantra has been putting the best five linemen on the field. What if that five includes Bitonio at tackle and Corbett at guard?
