2017–18 Detroit Pistons season: The 2017–18 Detroit Pistons season will be the 77th season of the franchise, the 70th in the National Basketball Association (NBA), and the first in Midtown Detroit.

Revision (writing): Revision is the stage in the writing process where the author reviews, alters, and amends her or his message, according to what has been written in the draft.  Revision follows drafting and precedes editing.  Drafting and revising often form a loop as a work moves back and forth between the two stages.  It is not uncommon for professional writers to go through many drafts and revisions before successfully creating an essay that is ready for the next stage: editing.

Detroit Pistons: The Detroit Pistons are an American professional basketball team based in Detroit, Michigan.  The Pistons compete in the National Basketball Association (NBA) as a member club of the league's Eastern Conference Central Division.  The team plays its home games at Little Caesars Arena and was founded in Fort Wayne, Indiana as the Fort Wayne (Zollner) Pistons in 1941, a member of the National Basketball League (NBL).  The Pistons joined the Basketball Association of America (BAA) in 1948.  In 1949, the NBL and BAA merged to become the NBA, and the Pistons became part of the merged league.  Since moving to Detroit in 1957, the Pistons have won three NBA championships in 1989, 1990 and 2004.

Honda CD200 RoadMaster: Honda introduced several 200 cc motorcycles with similar engines but different body variations in the 1980s.  The model introduced in South Africa and Pakistan was known as the CD200 RoadMaster.  It had a twin cylinder 10-degree cylinder angle with a 360-degree crank shaft angle engine which meant the pistons moved together and reached top dead centre (TDC) and bottom dead centre (BDC) at the same time.  It was a detuned version of the Honda CD185 twin.  The engine had the same bore as the CD185 but low compression pistons (8.8:1) with a bore and stroke of 53.0 x , compared to 9.0:1 Compression and 53.0 x for the CD185.  The result was less power, a higher fuel economy and a lower top speed.  The alternator system was also different from the CD185.  Apart from this the models were much similar, using the same frames, suspension, wheels, tyres, and brakes.

Detroit Falcons (basketball): The Detroit Falcons were a professional basketball team based in Detroit.  It played in the 1946–47 season in Basketball Association of America, a predecessor organization to the National Basketball Association.  The team folded after one season, leaving the Motor City without a professional basketball team until a decade later, when the Fort Wayne Pistons moved there.

Don Kojis: Donald R. Kojis (born January 15, 1939) is a former professional basketball player.  Born in Milwaukee, Wisconsin, he attended Marquette University and was drafted by the Chicago Packers in the second round (12th pick) of the 1961 NBA Draft.  He played forward for the Baltimore Bullets (1963–64), Detroit Pistons (1964–66), Chicago Bulls (1966–67) (acquired prior to the season via the expansion draft), San Diego Rockets (1967–70) (acquired prior to the 1967–68 season via the expansion draft), Seattle SuperSonics (1970–72) and Kansas City-Omaha Kings (1972–75).  Kojis was one of three players ever selected in expansion drafts held in consecutive years (Bob Weiss and George Wilson being the other two) (Wilson was selected in three consecutive expansion drafts).  Kojis was also one of a small number of players who played for three expansion teams (Kojis playing for the 1961–62 Packers, the 1966–67 Bulls, and the 1967–68 Rockets).

1957 NBA draft: The 1957 NBA draft was the 11th annual draft of the National Basketball Association (NBA).  The draft was held on April 17, 1957, before the 1957–58 season.  In this draft, eight NBA teams took turns selecting amateur U.S. college basketball players.  Prior to the draft, the Fort Wayne Pistons and the Rochester Royals relocated to Detroit and Cincinnati, and became the Detroit Pistons and the Cincinnati Royals respectively.  In each round, the teams select in reverse order of their win–loss record in the previous season.  The draft consisted of 14 rounds comprising 83 players selected.

List of Detroit Pistons head coaches: The Detroit Pistons are an American professional basketball team based in Auburn Hills, Michigan.  They play in the Central Division of the Eastern Conference in the National Basketball Association (NBA).  The team, owned by Tom Gores, plays its home games at The Palace of Auburn Hills.  The franchise was founded in 1941 by Fred Zollner as the Fort Wayne Zollner Pistons, playing in the National Basketball League (NBL).  In 1948, the team was renamed to the Fort Wayne Pistons and joined the Basketball Association of America (BAA), which merged with the NBL to become the NBA a year later.  After spending nine seasons in Fort Wayne, Indiana, Zollner moved the team to Detroit, Michigan in 1957 to be able to compete financially with other big city teams.  In the 1980s, general manager Jack McCloskey was instrumental in the Pistons' future championship runs by drafting Isiah Thomas, acquiring key players like Joe Dumars and Dennis Rodman and hiring head coach Chuck Daly.  The 1980s team, known today as "the Bad Boys" due to the physical playing style, eventually won two championships in the 1989 and 1990 NBA Finals under Daly.  The Pistons won their third title in the 2004 NBA Finals under the tenure of Larry Brown.

1988–89 Detroit Pistons season: The 1988-89 NBA season was the Pistons' 41st season in the NBA and 32nd season in the Detroit metropolitan area.  The Pistons moved from the Pontiac Silverdome to the brand-new Palace of Auburn Hills before the start of the season, which culminated in the Pistons' first NBA championship, sweeping the Lakers in four games in a rematch from last year's NBA Finals and avenging their NBA Finals loss.
