CLEVELAND, Ohio: Scribbles in my notebook after the Browns lost, 43-13, to the Tennessee Titans on Sunday at FirstEnergy Stadium:

1. After the game, coach Freddie Kitchens said: “We’re going to find out what kind of team we are now.” That’s true. And it’s also true that we’ll find out a lot about the coaching staff.

2. The Browns were ill-prepared and often overwhelmed in Sunday loss. Not even in the worst moments of the late 1999 expansion era were they flagged for 18 penalties and 182 yards. By contrast, Tennessee was flagged six times for 54 yards.

3. The Browns should have known what was coming, at least in terms of how Tennessee plays. The Titans are physical. They want the game to have very little flow. They will tempt an undisciplined team into losing its poise. None of this is a secret in NFL circles.

4. The Browns had two players ejected (Greg Robinson and Devaroe Lawrence). They also had Myles Garrett called for unsportsmanlike conduct. He was fortunate not to be ejected, as he threw a punch. Sheldon Richardson was called for roughing the passer.

5. To Garrett’s credit, he said this about throwing a punch: “I have to keep my composure. That’s on me ... (can’t) do dumb stuff like that."

6. Chris Hubbard had a dismal day. He opened the game at right tackle. After Robinson was ejected and backup left tackle Kendall Lamm departed with a knee injury, Hubbard moved to left tackle. No matter where he played, it was awful.

7. Hubbard gave up a sack early in the game leading to Baker Mayfield being tackled in the end zone for a safety. He was flagged for two holding penalties and a false start. Tight end Demetrius Harris also was nailed with a pair of holding penalties.

8. An excess of holding penalties and false starts happen when the offensive line is physically overmatched. The linemen are holding to protect their QB. Or they are moving before the snap, trying to get a first step on the man they are assigned to block.

9. What does this have to do with the coaching staff? The offensive line has real problems. The trade of Kevin Zeitler to the Giants removed a very good guard. Eric Kush replaced him. But the Browns lost a solid interior linemen who joined with veteran center JC Tretter and guard Joel Bitonio. That was a talented and experienced group, helping with run blocking and protecting the QB from a defensive rush up the middle.

10. The Browns will need to revamp the offensive line. It could be moving newcomer Wyatt Teller to right guard. Or doing something with the tackles.

11. The Browns blocked poorly in the third preseason game against Tampa Bay. I wrote about that and received some push back about taking the preseason too seriously. But that was the Browns starting O-line on the field for the first half in Tampa Bay, and they had problems blocking for the run and in pass protection.

12. Mayfield didn’t have much help in terms of pass protection. But he also wasn’t sharp after the first series of the game. He completed 5-of-6 passes on that 73-yard TD drive. But after that, he was 20-32 passing with zero TDs and three interceptions. He was sacked five times. The frustration level for him was high.

13. Mayfield said: “Anytime you get something going, you shoot yourself in the foot. That was our big problem ... not being able to build positive plays ... dumb penalties hurting ourselves, then obviously turnovers on my part.”

14. One of the most disturbing aspects of this game was the second half. The Browns were down 12-6. Tennessee obviously made some adjustments to change the game, especially Titans defensive coordinator Dean Pees. The Browns didn’t respond to anything the Titans did.

15. Can’t fault the Scottish Hammer. Jamie Gillan punted five times for a 46.6 average.
