This is one of the best, most honest interviews I've heard from Packer brass.

Yes, there's some politics and 'non-speak', but I was impressed with the following answers:

"Q: You and General Manager Ted Thompson work together closely on personnel decisions, but what happens when you two don't agree?

A: "It's not like we only have one conversation. I don't know how it works for you at the paper. There's times where you both see a player a little differently, but you talk about it all the time. It's not like you get to a point where I'm digging my heels in on this guy, and he digs his heels in on that guy. Maybe it happens that way other places, I don't know. I can only speak for us. We talk about these players all the time, so the things that he likes, I have the sense and the ability to see that, and he understands where I'm coming from. All the grades, everything that we have, we give to him. There's no information that's not shared. It's not (the personnel department) is down there, and we're over here. And it is like that some places. I've worked in that environment before. I think what happens is that you have such different opinions on one player, and frankly the communication between both groups is not there. That's why you'd have two different opinions. If you would talk about it the whole time and share the information, you could still disagree, but at least you have a better understanding of why he sees a player this way, and he will see why I see it that way. I've been involved where I've coached players, and I don't think the personnel department could give a hoot what I thought about him. Then when changes are made, that's why you sometimes have personnel guys or coaches say, 'Whoa, that move shocked me.' It's just a lack of communication."


And:


"Q: What position or position groups concern you the most going into the season as far as depth is concerned?

A: "I'm not really concerned about any position, but you're always concerned about your young players. I think that's a natural concern because rookie players, it's so new to them, it's a long season, you have to make sure you keep the environment that you created in training camp, in some way or fashion stays the same way when you get to the 53 because you have to make sure these guys progress. I don't know if you notice this, but when we practice, you see the coaches coach their guys during opponent drills. That's something that I instituted here. You see some places where the quality control guy is the only one running the drill. To me, that's counterproductive because the look's not as good, and the other part is the coaches are getting further away from their young players. So all of our coaches are in the drill coaching their guys, saying, 'Hey, this is the same as this is for us.' You've got to keep developing those younger players."

Here's another MM quote that I like, from another GBPG article:

"For the better part of eight months the Packers' coaches have been making adjustments and additions to their playbooks. With nobody showing much of anything in exhibition games, the laboratory doors swing open in September.

"I think the first two or three games is are 20 to 30% of what we called unscouted looks," McCarthy said. "So 20 to 30% of the game Sunday night, probably on both sides, will be something we haven’t seen before, and they haven’t seen before. You’re trying to find an edge."

McCarthy has talked to coordinators Joe Philbin and Dom Capers about keeping the "wild west" factor to a minimum.

"The trap you can fall into is, you've been preparing for this one game for so long and you've got so many good ideas," McCarthy said. "You're not as sharp because things aren't as repped as you would like."


I like the way MM thinks, he's a heads up, thinking coach.
