BEREA, Ohio – Nobody knows how much the Browns starters will play Friday against the Buccaneers. But head coach Freddie Kitchens did say this week that they won’t play at all in the final preseason game against the Lions.

That means Friday should be the last time we see the starting offensive line in game action until the season opener against the Titans on Sept. 8. The starting group in both preseason games so far has been Greg Robinson (LT), Joel Bitonio (LG), JC Tretter (C), Eric Kush (RG) and Chris Hubbard (RT).

While that group has had quite a bit of practice time over the last few weeks, they’ve gotten just 14 snaps (two drives) together in preseason games. That’s not a very big sample size, but here’s a breakdown of what we’ve seen so far.

Bitonio: 13 snaps, 11 pass blocking snaps, no pressures allowed, 82.4 pass blocking grade from Pro Football Focus.

Hubbard: 13 snaps, 11 pass blocking, two hurries, one false start penalty, 65.3 pass blocking grade.

Tretter: 13 snaps, 11 pass blocking, no pressures, 65.0 pass blocking grade.

Robinson: 17 snaps, 13 pass blocking, one sack and one hurry, 61.0 pass blocking grade.

Kush: 39 snaps (35 at right guard), 26 pass blocking, one hurry, 51.9 pass blocking grade.

That group didn’t let anyone touch Baker Mayfield on the opening drive against the Redskins, which ended with a touchdown. They managed 22 yards and one first down with Garrett Gilbert under center on the first series against the Colts. On that drive they had issues executing a screen on the opening play, Hubbard had a false start, and Kareem Hunt gained two yards on one carry.

Again, Kitchens hasn’t said how much the starters will play vs. the Buccaneers, but more than one non-hurry-up offense drive with Mayfield should provide a clearer picture of where the group is at.

Then there’s right guard, where much of the focus will be Friday. Kush has started both preseason games and taken the bulk of the first-team reps in practices the last few weeks. But Kitchens has yet to declare a winner in the competition for the starting spot. There’s no guarantee that he’ll do it this weekend.

“It depends on how they play, seriously,” Kitchens said. “I told those guys the other day, we have five practices (now only two) and two games. If that is too much pressure for you, then you are probably in the wrong business.

“Everything we have done is to try to prepare them for that situation and try to put pressure on them in the midst of practice. Can someone go from on the team to off the team in five practices and two games? Of course. Can someone go from off the team to on the team? Of course. Can somebody go from a backup to a starter? Yes.”

Which leads us to Austin Corbett and Drew Forbes, who have also been involved – to varying degrees -- in the right guard competition.

Here’s a closer look at their preseasons.

Corbett: 114 snaps (all at center), 76 pass blocking, one sack, one hit, one hurry, two holding penalties, 29.6 pass blocking grade.

Forbes: 83 snaps (75 at right guard, eight at left guard), 53 pass blocking, three hurries, one holding penalty, 62.6 pass blocking grade.

Kyle Kalis, who was rotating in a right guard with Corbett and Kush earlier in camp before missing time with a concussion, played 24 snaps, all at left guard, against the Redskins. In 15 pass blocking snaps he had a 73.4 grade with no pressures or penalties. But he did not return to practice this week and isn’t expected to play vs. the Buccaneers.

Offensive line coach James Campen said he is 100 percent certain the Browns have their right guard on the roster. But, like Kitchens, he isn’t predicting a decision following Friday’s game.

“We are going to go through the process in the third preseason (game), then you take a look at that tape and make some assessments there,” Campen said. “Hopefully, it is very apparent who that person is, but by no means is there anything set at this point in time. Just continue to work. Guys are rolling in and working well.”

Tackle Kendall Lamm has the second-best pass blocking grade (76.0) on the team this preseason. In 61 snaps (57 at left tackle) he has one hit and one hurry allowed. Brad Seaton has 104 snaps (second-most on the team this preseason behind Corbett). In splitting time between right tackle (74 snaps) and left tackle (30), and has a 75.0 pass blocking grade, with one hit and one hurry allowed.

We should see plenty of both players in the final two preseason games. Actually, all linemen who make the final 53-man roster as a backup will have to keep handy what they’ve learned in training camp and the preseason.

“It is a long season, and if you don’t get people in rotation and see in training camp, things can come bite you in the tail,” Campen said. “It could be Week 10 and someone loses a helmet for two or three series or before they get healthy and get back in or lose a shoe. You have to have some recall and remember what you did back in training camp. Moving guys around is a good thing.”
