NBA Coaches, Contemporary and Historical (Continued)

This is a follow up to my previous post here: http://www.blazersedge.com/2010/2/23/1322628/nba-coaches-contemporary-and

The previous post was about my search to answer whether previous professional coaching experience correlated with NBA championships won.  In the comments there was interest in expanding the sample size of coaches.  I started a spreadsheet to include all NBA coaches.  Part way through filling out the spreadsheet I realized I had made a few mistakes and was getting lazy on researching the previous coaching experience questions.  In short I had a hard time focusing while googling the 250+ NBA coaches.

I'm hoping you can help.  I have created a form presented here: http://www.colganc.com for entering information about a coach.  If each of you can enter the information of a few coaches we can increase the sample size to include all NBA coaches.  The form uses Google Docs and when completed and culled for obvious errors I will post the spreadsheet along with my own summary of the results.
