Problem:Question: How many teams did the NBA have the year the 20th annual draft took place? Passage 1:The new season brought a Cardinals team that was much changed from the one that went 100-62 in 2005 but fell to the Houston Astros in the NLCS. Starting pitcher Matt Morris, second baseman Mark Grudzielanek, left fielder Reggie Sanders, and relief pitcher Julián Tavárez left the team via free agency. Relief pitcher Ray King was traded to Colorado. Right fielder Larry Walker retired. Brought in to replace the departed Cardinals were right fielder Juan Encarnación, starting pitcher Sidney Ponson, relief pitchers Braden Looper and Ricardo Rincón, all via free agency, and second baseman Aaron Miles, acquired in the Ray King trade. Left field was left unsettled in the offseason and would remain so all year, with no player getting more than one-third of the playing time at that position.
 Passage 2:The 1966 NBA draft was the 20th annual draft of the National Basketball Association (NBA). The draft was held on May 11 and 12, 1966 before the 1966–67 season. In this draft, ten NBA teams took turns selecting amateur U.S. college basketball players. A player who had finished his four-year college eligibility was eligible for selection. If a player left college early, he would not be eligible for selection until his college class graduated. The first two picks in the draft belonged to the teams that finished last in each division, with the order determined by a coin flip. The New York Knicks won the coin flip and were awarded the first overall pick, while the Detroit Pistons were awarded the second pick. This draft was the first to use the coin flip method, which replace the territorial pick rule. The remaining first-round picks and the subsequent rounds were assigned to teams in reverse order of their win–loss record in the previous season. An expansion franchise, the Chicago Bulls, took part in the NBA Draft for the first time and were assigned the last pick of each round. The draft consisted of 19 rounds comprising 112 players selected.
 Passage 3:Taylor started his career as captain of the football academy at Accrington and Rossendale College, also representing the England College side. He also spent some time on trial with Bury and Scunthorpe United. In the summer of 2011, Taylor spent time on trial at Football League Two side Accrington Stanley for pre-season after being recommended by former Stanley coach Paul Lodge. In August 2011 after a successful trial, Taylor joined Stanley permanently initially on non-contract terms. He made his professional debut for the club in the same month, coming on as a substitute for Kurtis Guthrie in the 2–0 defeat to Scunthorpe United in the Football League Cup. Later in August, Taylor signed a six-month professional contract with the club, opting to turn down the chance to attend university to study a sports degree. His league debut came in a 2–1 defeat to Southend United. His first start and final appearance for Stanley came in a 1–0 win over Bradford City. In January 2012, Taylor was released from his contract by mutual consent. In February 2012, Taylor joined Northern Premier League Division One North side Clitheroe, making his debut in a 2–0 defeat to Ossett Town. He made a total of ten appearances for Clitheroe with his final appearance coming in a defeat to AFC Fylde in April 2012. His spell at Clitheroe was short and Taylor joined North West Counties Football League First Division side Nelson in November 2012. Taylor impressed in his first season with the club as Nelson finished in mid-table. He signed a new one-year contract in July 2013, turning down a number of clubs higher up the football pyramid. In August 2013, after a bright start to the season he suffered a fractured fibula and was out of action for five months. In January 2014, after making a full recovery, he returned to first team training. He finished the season with seven appearances and one goal as Nelson were crowned champions and gained promotion to the NWCFL Premier Division. In May 2014, Taylor committed himself to Nelson for another season.
