and calls a timeout); in the NBA and WNBA, only the opposing team can call a timeout after a basket is made. From the 2015–16 season through 2018–19, NCAA men's coaches were banned from calling timeouts from the bench while the ball is live at any time in the game; from 2019 to 2020, they are again allowed to call such timeouts, but only during the last 2 minutes of any period (half or overtime). Players have not been subject to this restriction. In addition, the NBA limits what types of defense a team can play, primarily in an effort to prevent coaches from slowing down the pace of the game by using zone defenses. Zone defense is permitted in the NBA and WNBA; however, players cannot stand in the lane for more than three seconds if they are not guarding anyone. In NCAA basketball, no such restriction exists, and coaches are free to design a variety of defensive techniques. In college basketball, it is required by rule that the home team wears their white or light-colored jerseys while the visiting team wears their darker jersey color. The NBA, like most other professional sports leagues, lets the home team decide which uniform to wear, but with a few exceptions the home team has continued the tradition of the college game and wears white (or in the case of the Los Angeles Lakers for non-Sunday home games, gold) at home. Since the 2017–18 season, the NBA only requires that road teams wear colors that contrast sufficiently with the home team's choice, meaning that "color on color" games are now possible. This is for regular season play only; home teams always wear white during the playoffs. The WNBA, however, follows the college rule for all games. The NBA introduced a new dress code rule in 2005. Now players are required to wear business casual attire whenever they are engaged in team or league business. This includes a long or short-sleeved dress shirt (collared or turtleneck), and/or a sweater; dress slacks, khaki pants, or dress jeans, and appropriate shoes and socks, including dress shoes, dress boots, or other presentable shoes, but not including sneakers, sandals, flip-flops, or work boots. The WNBA has a similar dress code, adjusted for standard women's attire. NCAA rules have no set dress code rule, leaving it up to individual teams or conferences. The organizations also have different rules
