Larry Zierlein, the Steelers Offensive Line Coach seems very conservative.

He's 61 years old.

I have been doing a Psychology Profile on him similar to that of the CIA and KGB.

I must study him from afar so we will use the forensic psychology that the FBI uses to track down serial killers; by studying their actions we will get a mental make-up of the suspect.

By having Sean Mahan starting right now, that tells me that he is scared of Justin Hartwig being injury prone.

His worst fear is having Kemo and Hartwig in the starting line-up and both of them getting injured and than they will be forced to play musical chairs in mid-season and reshuffling the entire Offensive Line.

He would put Hartwig in the starting line-up if he is a lot better than Mahan. If he is only slightly better than Mahan than he would rather go with the guy who is less injury prone.

For further evaluation of subject Larry Zierlein I would need him to take the Briggs Myers Personality Profile Test; which is the same exam that the CIA gives it's recruits.

This will tell us what happens to him under stressful situations.

You can take the test here for free:
