Dak wasn't the only reason they lost last night but he was a big reason he lost. His first pass of the game to a wide open TE and he sails it over the guys head by 10 feet. This is Dak. When the 49ers scored on their first drive, it was important for Dallas to go down the field and answer that. Instead they spent 16 seconds going 3 and out.
Dak is not responsible for how the defense could not stop the 49ers all night. He could not stop Purdy, a 7th round draft pick, from dropping perfect passes to his receivers in stride. But he could have answered with some quality play of his own. Dak was pressing from teh moment he stepped onto the field, and it showed.
