First of all this is a McGinn story He is wrong 3 or 4 times more than he is right. When he is right so is everyone else in the world.
Next he double talks as he plays up the importance of his "expert".
An experienced executive in personnel for a National Football League team
He is a scout. He may be the head scout for a team but very few scouts are considered executives. That term is used for Presidents, VPs, GMs and a few other key staff people. If he was an executive he would not be referred to as a scout.
Selected because of his level of expertise and success in the NFL,
Sounds like a McGinn drinking buddy. A successful scout would actually be promoted beyond the scout level. McGinn would only use this man as his source if the scout supported McGinn's theory.
he has studied the Packers this summer, this September and for years before that.
Ok he is a scout in the NFC North division. A scout for San Diego for example would be familiar with the GB organization but would not scout them every single year extensively enough to have an accurate opinion on every player on the team. So what do you want a scout for divisional rival to say publicly? That GB has the greatest team around? Not really he is going to criticize it as much as he can. He will down play their abilities and magnify their weaknesses.
Even with all this scouts get their appraisals wrong all the time. Just look at draft day. They fail on the evaluations as much or more than they get right.
I feel much better about the Packers knowing McGinn and his buddy think they will finish 8-8.
