Analysis of information sources in references of the Wikipedia article "Bob Nelson (defensive tackle)" in English language version.
Nelson was a nose tackle who, because of a ratings error, was given unnatural acceleration ability. Coupled with his position, this made him king of the typically outlawed "Nose Tackle Dive," in which your nose tackle makes a slight move and dives, instantly sacking the quarterback on most pass plays.
The real-life Nelson had three sacks in three years as the Packers' nose tackle. The video game Nelson was an inexplainable, unstoppable force whose use is often legislated out of play because of the unfairness of it all.
