Pat Conroy called
Fifth Quarter "the best book about football I've ever read—and Jennifer Allen never played a down in her life." In
The Washington Post, Jonathan Yardley reviewed the book, noting that in writing about her father, she "illuminates his innermost soul and gives us not just a football coach but a human being.” The memoir contains claims that George held her by her feet over
Niagara Falls, struck her boyfriend in the head with a
pool cue, threw his brother Bruce through a glass sliding door, tackled his brother Gregory, breaking his collarbone, and dragged Jennifer upstairs by her hair. In the book, she wrote, "George hoped someday to become a dentist...George said he saw dentistry as a perfect profession—getting paid to make people suffer." With regard to the pool cue incident, she claimed it was a joke and that "Allen was simply testing her boyfriend's reflexes." With regard to the dentist quote, Allen claims that the book was a "novelization of the past" and written from the perspective of a young girl "surrounded by older brothers and a larger-than-life father." She claims to have a great relationship with her brother and noted that George walked her down the aisle at her wedding. ==Career==
