The new changes are, as usual, very convenient for the improvement of the game. The problem is not the changes themselves, but the result we have all seen last saturday. I don´t think that a few more passing or a few faster pace could account for the observed results. There is probably some mistake or a bug like the one observed at the beginning at scrimmages (OD ratings using the RB skills instead of OD rating).
Some message are maybe not very helpful for BBs, but other with describes the strage things that happened last saturday, are probably really important for them in order to get our feedback of what was happening.
So, a better zone defense is good for everybody, but only if this is properly implemented. Now, we don´t know what exactly was the problem, so the only thing we can do is reporting the problem we observed.
Debate is not about changes yes or not, but whether changes were working as expected or not.
