I really don’t get KMs struggles with the Bolts. Herbert is super arm talented, they have WRs, an RB, and have actually taken a big step backwards this year. Makes you wonder what our offenses could’ve put up ditching KM sooner.
I always thought KMs system might work well with Brady or Manning running it, a QB who is nearly flawless in reads and ball placement always but Dak certainly isn’t that. I think Dak needed a better system for him and that appears to be what MM has given him. Dak has shone brightly since.
Its my understanding that Garrett's system was similar to Norv Turner's system and its a descendant of the Air Coryell passing game. I think that is why Jerry was so patient with it because he saw it work.
That said, why it worked with Aikman and Irvin and others was a massive amount of repetition and a good bit of discipline. Aikman knew where Irvin was going, Novacek, etc.
When you look at some of the bad throws from Dak over the past few years they frequently were the result of him and the receiver not being on the same page. A guy would break differently than Dak expected. Overall, I just don't think that KM has the discipline to really implement this system correctly and it bites him at the wrong time.
From what I understand, the MM system really takes a lot of this out of play. The QB reads are simpler, the WR options are reduced, etc. There is just less statistical room for mistakes and that is bearing itself out with higher completion percentages and lower INT rates.
