The 2014 Portland State Vikings football team represented Portland State University in the 2014 NCAA Division I FCS football season. They were led by fifth year head coach Nigel Burton and played their home games at Providence Park. They were a member of the Big Sky Conference. They finished the season 3–9, 2–6 in Big Sky play to finish in a three way tie for tenth place.
Nigel Burton was a university football coach in 2013.
The context states that Nigel Burton had been coaching the Portland State Vikings (a university football team) for 5 years in 2014. This means that he must have coached them in 2013. The system may have had difficultly with this because it couldn't understand that it needed to solve a simple math problem in order to learn whether the statement was correct.
