One of the more talked about parts of the San Francisco 49ers loss to the Chicago Bears was the ending. On fourth and four, Nick Mullens start running around the sidelines and had a clear, easy path to the first down marker. Instead of getting the necessary yardage and running out of bounds, Mullens instead went for it all and tossed it to Marquise Goodwin, which fell incomplete.
It was an obvious mistake by a young quarterback. The down, distance, and time remaining are three things a quarterback must always be aware of, and in that situation, unless if the guy is wide open (which Goodwin was not), a matter of seconds remain in the game, you need to show better awareness.
