I don't see a lot of change in the offensive strategy even though McC isn't known as a run game guy but he has used his backs well when he's had them and even converted a WR to RB.
I think the main improvement they're after is scoring TD's when the opportunity is there. They were the #1 O between the 20's but they had to make long drives and when they got inside the opponents 20, they seem to freeze up and get overly cautious. They only halfway fix that and this O will be able to go up against any team.
I think this offense will respond because I think the real problem that this team had last season has been at least temporarily fixed, lack of confidence in coaching. When a team senses their HC is trying not to lose, that affects everything about a team but particularly in crunch time. This was not a team that exhibited that confidence of a team that knows their HC has their back, he'll go to the wall for them. A good HC must believe in his team in order for them to believe in him.
I think we really don't know about this Mike McCarthy. Man gets fired and watches his successor succeed in his first year with his team has some scores to settle within himself. The rumors are there about the rift between him and the high risk QB that could put his team on his back with his arm. That is not this QB, he's not that accurate, I've never seen a QB as accurate as Rodgers. You have a weapon like that, you call the game a little differently.
One thing I really like about McC and the main reason I wanted him, he knows how to use his weapons and other than QB, he's never had any team this loaded with them. His job is to keep everybody happy by keeping them involved.
The other element to this is Kellen Moore. If you watched him at Boise State, particularly his last season when Peterson was letting him be the on the field OC, he's aggressive and is a down the field kind of guy. If McC turns him loose, this could really be fun to watch because Moore is not a protect the D play caller, his strategy is to take the other O out of their game. If you recall, that was our 2014 team and why they led the league in turnover margin and were 2nd in picks. They pressured the other team to make tactical changes in their offense and heighten the risk factor.
