I truly think a lot of it has to do with going back and again lining the RB back about 8 yrds behind the LOS. I've been yelling at my TV the last 3 yrs for them to do this. Since GD came with his spread O with the QB always in shotgun, the RB's were lining up close which I don't think allowed the holes to open up when the RB was going through. The timing wasn't there. Prior to GD, they did line the RB up about 8 yards behind. See the successful years with Russell, Green, etc.. They got away from it the past few years. I think having Wiesman could have been a reason as well to line up closer.
Anyway, you can now see the zone blocking scheme work again and the timing seems to be like it used to be with the hole opening up at the ideal time for the RB to power through. Also, it's nice to see the counter run again which is a great play with lining up the RB that far back.
My opinion, but I think it has a bearing on the success.
