Stop blaming the coaches all the time! You have to be able to understand that they are not playing in the game. You can have the best game plan in the world, but if the player don't execute you cannot blame the coaches.
On the other side of the coin, if you think it's all on the coaches, do you think they told Dak to throw all those picks and fumble all those balls? The defense in the 49'er game held them to a low score and Dak threw it away wit two picks...I guess because the coaches told him to.
