Premature End, 30 Years of Fired Coaches in NBA

With inevitable early departure of Kurt Rambis from Timberwolves I wondered…
Which NBA Team have Fired Most Coaches in the Last 30 Years?
And How many of them Left Early on Their Own Terms?

So I visited Professional Basketball Transactions Archive and here’s what I’ve found…
Starting with curiosities…

Did you know there were three trades involving coaches in that period?
On 1983-06-07 Nets traded rights to Fred Roberts, 1983 second round pick (#46-Kevin Williams) to Spurs who agreed to release head coach Stan Albeck from his contract, thus allowing Nets to sign him.
On 2003-06-11 Rockets sent to Knicks second round pick (2005 #54-Dijon Thompson) as compensation for agreeing to release head coach Jeff Van Gundy from his contract and on 2007-06-06 Magic sent 2008 second round pick (#52-Darnell Jackson) to Heat as a compensation for head coach Stan Van Gundy.
Wow, those Van Gundy brothers were a valuable commodity ;-)

Back to the point, with another fired head coach, how will Timberwolves look historically?
