I wanted to see what the coaches records where in the last ten years and ended up going a little further. Here are the results.
Isiah Thomas: 2006-07 to present
35 - 58
Larry Brown 2005-06
23 -59
Herb Williams 2003-04 to 2004-05
17 -27
Lenny Wilkens 2003-04 to 2004-05
40 -41
Don Chaney 2001-02 to 2003-04
72 - 112
Jeff Van Gundy 1995-96 to 2001-02
248 - 172 
For a .590 winning % and two 50+ game winning seasons, over seven seasons.
Pat Riley 1991-92 to 1994-95
223 - 105 
For an average of over 55 wins a season, over four seasons.
I wish they never let Riley go

This guy is averaging over 52 wins a season in his 22 year coaching career.
I'll never trust this' team again.
