The 2013 Duke Blue Devils football team represented Duke University in the 2013 NCAA Division I FBS football season. The team was led by head coach David Cutcliffe, in his sixth year, and played its home games at Wallace Wade Stadium in Durham, North Carolina. Duke competed as a member of the Atlantic Coast Conference (ACC) in the Coastal Division.
David Cutcliffe began coaching the Duke Blue Devils football team in 2013.
It's definitely incorrect because the 2013 season was his sixth year as coach. It's difficult for the system because it probably doesn't understand what it means to begin a coaching career and judged the statement to be true due to the sentence that just mentioned he was coaching the team in 2013.
