The pressure is mounting on Sacramento Kings coach Luke Walton — again. With the Kings (5-8) in the midst of a four-game losing streak heading into a Monday night game at Detroit, sources say the third-year coach’s job status will likely be in peril soon if the current slide continues. The Kings, who started the season 5-4 before falling to Indiana, Phoenix, San Antonio and Oklahoma City, are determined to break their 15-year playoff drought, the NBA’s longest, and Walton won’t be given the same leeway to turn things around as he was last season. Especially when it comes to extended losing streaks.
