BBAO: Ndamukong Suh didn't cross line

We're Black and Blue All Over:

I'll say it again: I don't think that Detroit Lions defensive tackle Ndamukong Suh's 15-yard penalty in Friday night's preseason opener was anywhere close to the penalty he earned last summer for ripping off the helmet of Cleveland Browns quarterback Jake Delhomme. Friday night, he hit Cincinnati Bengals quarterback Andy Dalton and Dalton's helmet came off -- an important distinction.

Obviously, the violence of the hit had something to do with the helmet coming off. But it didn't strike me as blatantly dirty. Neither did Suh.

Suh, via Carlos Monarrez of the Detroit Free Press: "There's always a fine line of dirtiness and a fine line of aggressiveness. I know to this point that in my own heart that I haven't crossed that line by any means."

If anything, the hit just puts another incident on tape for two entities: opposing quarterbacks and future game officials. Both will have a close eye on him in upcoming games.

Continuing around the NFC North:

  • Lions receiver Calvin Johnson is day-to-day because of a bruised left shoulder, according to Phillip Zaroo of Mlive.com.

  • Lions tight end Brandon Pettigrew (ankle) returned to practice on Sunday, notes Tim Twentyman of the Detroit News.

  • Lions receiver Nate Burleson hopes that teams single-cover Johnson this season, as ESPN analyst Cris Carter recently suggested. Monarrez has more in the Free Press.

  • Chicago Bears defensive end Corey Wootton will miss at least a month because of damage to the meniscus in his right knee, according to Vaughn McClure of the Chicago Tribune. Wootton suffered the injury on the opening kickoff of Saturday's preseason opener.

  • With 73 yards on 13 carries, and another 46 yards on two catches, Chicago running back Kahlil Bell is getting noticed. Sean Jensen of the Chicago Sun-Times has more.

  • Bob LeGere of the Daily Herald thinks the Bears need to move Roberto Garza back to guard and insert Chris Spencer as their starting center.

  • Bears rookie offensive lineman Gabe Carimi was solid in his preseason debut at right tackle, according to Dan Pompei of the Tribune.

  • Michael C. Wright of ESPNChicago.com on the Bears' offensive line: "The whole unit needs to improve. But reflection usually offers clarity, and a day after what appeared to be a nine-sack debacle at Soldier Field, the truth is that what transpired really wasn't out of the realm of what was expected."

  • Backup quarterbacks Matt Flynn and Graham Harrell both played well Saturday night, writes Jason Wilde of ESPNMilwaukee.com.

  • Tom Silverstein of the Milwaukee Journal Sentinel: "Competition is supposed to make you better, but if you're the Green Bay Packers, you might not want to bring in a punter for, say, the next 10 years. Not with Tim Masthay on the roster."

  • Rob Demovsky of the Green Bay Press-Gazette: "Early in training camp, Randall Cobb insisted he can be more than just a slot receiver, which was what many scouts had him pegged for coming out of the University of Kentucky. Even if he's limited to that role as a rookie this season, it looks like he might be able to do some damage."

  • The Minnesota Vikings appear to be moving away from the zone-blocking run scheme, writes Tom Pelissero of 1500ESPN.com.

  • Bob Sansevere of the St. Paul Pioneer Press pulls back the curtain on new Minnesota Vikings defensive coordinator Fred Pagac. A little bit.

  • The Vikings had a tight end next to new left tackle Charlie Johnson on eight of his 11 plays over the first two series of Saturday's preseason opener, notes Judd Zulgad of the Star Tribune.
