FOXBORO — No one has to tell Logan Mankins what can happen if you don’t bring your best against the likes of Ndamukong Suh and the Lions defensive line.

Just take a look at what happened to Bengals rookie Andy Dalton in his first game in the NFL.

Two things about this hit: A) Suh didn’t even get credit for a sack (nor did he register one or even a tackle in the game) and B) he was leveled with a $20,000 fine.

Obviously, Tom Brady and the Patriots have been around the block a little longer and with more stability than the Cincinnati offensive line but still, the lesson delivered by Suh, Kyle Vanden Bosch and Corey Williams of two weeks ago will be taught this week in Foxboro by professor Bill Belichick.

“Well, they’ve got good players,” Mankins said before Monday’s practice. “Suh, he’s a really good player. Vanden Bosch, Williams, across the board they’ve got good players that are strong and play with a good style so it’s always a challenge.

“They’re very good across the front. And in our room, our O-line room, we all know we need to make improvements and this will be a good week to see if we made any.”

Suh did manage to sack Brady once last year in New England’s 45-24 win on Thanksgiving Day so Mankins and company will be on guard.

“Not so much stunned, but that’s going to happen when you go against good players, they’re going to get your sometimes, you gotta be ready for it and do the right things and be in the right position or guys with that talent level are going to take advantage of it.”

Right now for Mankins, it’s all about technique as camp closed Saturday and regular practices began Monday.

“For offensive lineman, the main thing is technique,” he said. “And when you’re out there and your feet are jumping around and your hands aren’t hitting where you want them to, that’s something you need to get corrected or it’s going to catch up with you down the road.”

He laughed when asked if he had any idea if this third preseason game will be like years past when the regulars would play into the second half in some cases.

“Haha, I don’t know,” he said. “Bill, he runs that around here. I doubt he’d give you any insight into what his plans are, we’re usually in the dark like you guys, so I don’t know what the plans are. Whatever he feels is best for the team, we’ll agree with that.

“We’re prepared to play 60 minutes, and if you get to come out early, you get to come out, if you’re in the game for the whole time, you’re in the game the whole time. You go into the preseason game like it’s a regular season game ready to go and if you get to come out, you get to come out.”
