I want to know the answer to the following question:
How many students at Notre Dame received the Heisman Trophy?
All the background I'm provided with is that "The football team, an Independent, has accumulated eleven consensus national championships, seven Heisman Trophy winners, 62 members in the College Football Hall of Fame and 13 members in the Pro Football Hall of Fame and is considered one of the most famed and successful college football teams in history.". Is that enough to answer the question?
