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.
