When news that the Boston Celtics were hiring Ime Udoka as their next head coach was released...ESPN's Jay Williams took to Twitter to issue his response. He was thrilled the Celtics finally hired their first black head coach in franchise history.

Of course...Jay Williams was way off base...the Celtics have had five black head coaches. When they hired Bill Russell back in the 1960s...he was the first African American head coach in the NBA. 

Clearly Jay Williams has lost all credibility...but this tweet isn't the reason. We reveal the REAL reason Jay Williams lost all credibility this week.
