He traded away both Silas and Westphal because they wanted salary increases that would have made them higher earners than the best player on the Celtics (Cowens), which was not acceptable to Auerbach. While the Westphal trade to the Phoenix Suns in exchange for Charlie Scott was considered a success due to the Celtics' 13th title in 1976, Auerbach later admitted he erred in letting Silas go, even after Cowens personally begged him to give Silas a new deal. When Havlicek retired in 1978, the Celtics went 61–103 in two seasons.[1] In the summer of 1978, after the worst in a string of contentious clashes with several different owners after Walter Brown's passing in 1964, Auerbach hopped into a taxi to take him to Logan Airport, where he was to board a flight to New York to consider a lucrative contract offer from Knicks owner Sonny Werblin.
