Carolina Panthers quarterback Cam Newton had 10 rushing touchdowns in his first 11 NFL games, breaking the single-season rookie record for a quarterback. Vince Young, who rushed for seven scores as a first-year player in 2006, held the record before Newton.
At the time of this article, Newton was on pace to break the single-season record for most rushing touchdowns by a quarterback — not just rookie quarterbacks.* Steve Grogan holds that distinction; he rushed for 12 touchdowns in 1976, his second year as a pro. Grogan's mark is a 35-year-old record. It is not, as stated in this article, a "35-year-old rookie record."
Oh, well. Perhaps the writer was in his first year as a pro. With more experience, rookie mistakes like this will be a thing of the past.
* Newton did break the record. He finished with 14 rushing touchdowns in the 2011 season.
