PRO BASKETBALL—The week went from bad to worse for New York. On Tuesday Midwest Division leader San Antonio defeated the Knicks 114-91, as New York fans booed Knick newcomer Paul Westphal after cheering him in his debut three nights earlier. Next, the Knicks suspended Forward Sly Williams, who had skipped a practice, without pay for what they termed "violations of club policy." It was the second time in six weeks. Williams' suspension was lifted two days later, but then Williams skipped the next scheduled practice. He showed up for Saturday night's game against Atlanta and scored four points, but Atlanta won 104-98.
