Question: The author of "Personal Foul: A First-Person Account of the Scandal That Rocked the NBA" refereed in the NBA for how many seasons?
Context: In basketball, a personal foul is a breach of the rules that concerns illegal personal contact with an opponent.  It is the most common type of foul in basketball.  A foul out occurs when a player exceeds his or her personal foul limit for a game and is disqualified from participation in the remainder of the game. In basketball, a flop is an intentional fall by a player after little or no physical contact by an opposing player in order to draw a personal foul call by an official against the opponent.  The move is sometimes called "acting", as in "acting as if he was fouled".  Because it is inherently designed to deceive the official, flopping is generally considered to be unsportsmanlike.  Nonetheless, it is widely practiced and even perfected by many professional players.  The player that commits the act is referred to as a "flopper". In basketball, a flagrant foul is a serious personal foul.  A foul is considered flagrant when it involves excessive or violent contact that could injure the fouled player.  A flagrant foul may be unintentional or purposeful; the latter type is simultaneously known as an "intentional foul" in the NBA.  However, most intentional fouls are not considered "flagrant" and are performed safely as a necessity for time management. Norman "Norm" Grekin (June 22, 1930 – September 29, 1981) was an American professional basketball player.  Grekin was selected in the 1953 NBA draft by the Philadelphia Warriors after a collegiate career at La Salle.  He played in his only career game on October 31, 1953.  He recorded one personal foul. Ayuba Suleiman Diallo (17011773), also known as Job ben Solomon, was a famous Muslim who was a victim of the Atlantic slave trade.  Born in Bundu, Senegal (West Africa), Ayuba's memoirs were published as one of the earliest slave narratives, that is, a first-person account of the slave trade, in Thomas Bluett's "Some Memories of the Life of Job, the Son of the Solomon High Priest of Boonda in Africa; Who was enslaved about two Years in Maryland; and afterwards being brought to England, was set free, and sent to his native Land in the Year 1734".  However, this version is not a first-person account.  A first hand account of Ayuba's capture and eventual return home can be found in Francis Moore's "Travels into the Interior Parts of Africa". The Comforts of Madness is the debut novel of English author Paul Sayer.  It won the 1988 Whitbread Award for both Best First Novel, and Book of the Year.  Written while the author was working as a psychiatric nurse in Clifton Hospital in York, and drawing on his own experiences it is a first-person account of a speechless, catatonic patient in a hospital therapy unit. In basketball, a technical foul (also colloquially known as a "T" or a "Tech") is any infraction of the rules penalized as a foul which does not involve physical contact during the course of play between opposing players on the court, or is a foul by a non-player.  The most common technical foul is for unsportsmanlike conduct.  Technical fouls can be assessed against players, bench personnel, the entire team (often called a bench technical), or even the crowd.  These fouls, and their penalties, are more serious than a personal foul, but not necessarily as serious as a flagrant foul (an ejectable offense in leagues below the NBA, and potentially so in the NBA). Personal Foul: A First-Person Account of the Scandal That Rocked the NBA is an autobiography written by former National Basketball Association (NBA) referee Tim Donaghy and published by Florida-based VTi-Group, Inc. in December, 2009.  Donaghy, who had resigned from the league as a central figure in the 2007 NBA betting scandal, describes his involvement in and inner workings of the scandal, as well as his gambling addiction. Tim Donaghy ( ; born January 7, 1967) is a former professional basketball referee who worked in the National Basketball Association (NBA) for 13 seasons from 1994 to 2007.  During his career in the NBA, Donaghy officiated in 772 regular season games and 20 playoff games. Avitus of Braga (Latin Avitus Bracarensis) was an early fifth-century literary priest of Braga (Portugal), who travelled to consult with Augustine and attend the Council of Jerusalem (415) that found against Pelagius.  He is remembered for having produced a Latin translation of the first-person account of the miraculous finding of Saint Stephen's tomb near Jerusalem in 415, which he prefaced by a general letter.  His personal concern was embodied in relics of the Protomartyr, which would have encouraged the pilgrimage trade at Braga and which he entrusted to Paulus Orosius, also of Braga, to deliver there.  Orosius, however, reaching Majorca and hearing daunting news of conditions in Hispania, which was disordered by the invasion of the Vandals, left the relics, which have disappeared, and returned to North Africa.
