I'm not going to defend, or offend any single player over others in the fact that the game of Football is one of the most intricate and complex of games and how many players, at the same time, are involved to both do their job and outperform their opponents play after play after play after play under the direction of a Third Party is certainly a daunting task.
And they are going against opponents that are professionals themselves and doing their hardest to defeat what's in front of them and what their assignments are and things can happen from a slip of the foot to the slide of a shoulder pad push that can make someone else to look bad as they pass off players, or things like that.
I cannot be truthful to myself to myself to say I KNOW what the issue is, but I feel fairly certain it's never one thing.
It's many things and for many reasons.
Now, like I said: I'm defending anyone, including Dak.
I just never place a game's blame on one single person because there were so many plays that included so many players and coaches that leads up to the outcome.
Important plays are to be looked, but how did game go to get to that point?
TLDR: I place the blame upon both of them and the entire offensive team as a whole because Football is a Team game with many players and many assignments over many, many plays.
