Answer the question at the end by quoting:

Thomas Michael Cousineau (born May 6, 1957) is an American former college and professional football player who was a linebacker in the Canadian Football League (CFL) and National Football League (NFL) for nine seasons during the 1970s and 1980s. He played college football for Ohio State University, and twice earned All-American honors. He was the first overall pick of the 1979 NFL Draft, and played professionally for the CFL's Montreal Alouettes and the NFL's Cleveland Browns and San Francisco 49ers. Cousineau is a member of the College Football Hall of Fame, elected in the class of 2016.
Cousineau attended Ohio State University, where he played for legendary coach Woody Hayes' Ohio State Buckeyes football team from 1975 to 1978. During that span, Ohio State had an overall record of 36-10-2 and 28-4 in the Big Ten, were three-time Big Ten champs. The Buckeyes played four bowl games after each of the seasons he played: in the Rose Bowl, Orange Bowl, Sugar Bowl and Gator Bowl. They were a Top 5 team for 36 weeks over these four years and the No. 1 team in the nation for eight weeks in 1975, and ultimately finished fourth, sixth and 12th in the final Associated Press polls in 1975, 1976 and 1977, respectively. Cousineau majored in marketing. It is rumored that he frequently ate Ken Boock's lunch while attending Ohio State. He was a consensus first-team All-American, breaking the school record with 211 tackles in a single season in 1978, an average of 17.5 a game. He also broke the school record for most tackles in a game with 29 against Penn State in 1978, and was the MVP of the 1977 Orange Bowl. Cousineau's last game for the Buckeyes was the infamous 1978 Gator Bowl against Clemson, during which Coach Hayes punched Clemson linebacker Charlie Bauman in the final minutes of the game. Hayes was fired the following day for the incident. Cousineau still holds many of Ohio State's tackling records. As of 2016, he holds six of the top 10 single-game tackling records, 29 single-game tackles (since tied by fellow College Football Hall of Famer Chris Spielman), most solo tackles in a single game, (16 against SMU in 1978). He also ranks second on both the all-time OSU tackle list with 569 (three behind Marcus Marek) and on the career solo tackles list with 259. He was named an All-American in 1977 and 1978. The Chicago Tribune named him the MVP of the Big Ten in 1978. He graduated from OSU in 1979. In 2016, he became the 25th Ohio State player, along with seven Buckeye coaches, to be named to the College Football Hall of Fame.

What were his stats there?

IN: Chapter 27 is a 2007 biographical drama film depicting the murder of John Lennon by Mark David Chapman. It was written and directed by Jarrett Schaefer, based on the book Let Me Take You Down by Jack Jones, produced by Robert Salerno, and stars Jared Leto as Chapman. The film takes place in December 1980, and is intended to be an exploration of Chapman's psyche. Its title is a reference to J. D. Salinger's novel The Catcher in the Rye, which has twenty-six chapters, and suggests a continuation of the book.

The script took Schaefer four years to write, but when it was finished, the film came together quickly. With the help of producers Alexandra Milchan and Robert Salerno, Schaefer cast Jared Leto as Mark David Chapman. For his role, Leto gained 67 pounds (30 kg) by drinking microwaved pints of ice cream mixed with soy sauce and olive oil every night. Gaining the weight, he said, was tougher than dieting himself into skeletal shape for his role as drug addict Harry Goldfarb in Requiem for a Dream (2000). The abruptness of Leto's weight gain gave him gout. He had to use a wheelchair due to the stress of the sudden increase in weight put on his body. After the shooting of the film, Leto quickly went on a liquid diet. He explained, "I've been fasting ever since. I've been doing this very strange, like, lemon and cayenne pepper and water fast. I didn't eat any food for 10 days straight; I think I lost 20 pounds that first 10 days." Losing the excess weight after Chapter 27 proved a challenge. "It took about a year to get back to a place that felt semi-normal," he said; "I don't know if I'll ever be back to the place I was physically. I'd never do it again; it definitely gave me some problems." Twenty-two years prior to this film's production, actor Mark Lindsay Chapman, while professionally using the name Mark Lindsay, had been almost cast as John Lennon in the biopic John and Yoko: A Love Story (1985). Yoko Ono had been deeply involved in the production and had herself been initially impressed with his audition and approved his casting prior to discovering his full name was Mark Lindsay Chapman. She then nixed his casting on the grounds it was "bad karma", and a great deal of press attention was given to his having almost gotten the role. The director of Chapter 27, Jarrett Schaefer, auditioned many Lennon impersonators, but was especially impressed with Mark Lindsay Chapman's tape because he conveyed the "tough town" street-smart quality of Lennon that the impersonators failed to convey, as they always played Lennon as larger-than-life. Schaefer described Lennon as having a "chip on his shoulder and always cracking these cynical one-liners", and felt that actor Chapman was best at conveying this quality. Schaefer had some difficulty negotiating the casting with the film's producers because of Chapman's name. After Chapman was cast, he asked Chapman how he should be billed to which Chapman replied "Mark fucking Lindsay Chapman. That's my fucking name." Schaefer remarks that this was so reflective of how Lennon talked, it just reinforced his sense that Chapman was right for the part.

During filming what was some obstacles if any?
