The presense of an index is not necessarly a problem even if the index is not used. In your article you failed to state what problem you were trying to solve. If index analaysis were as simple as looking at the numbers SSMS would have a button to delete them or perhaps just delete them on it's own.

Your have apparently not bothered to speak with the develpers to find out why those indexes are there and then taken the opportunity to educate so you won't find the same thing in the next project to hit production.

I suspect those who refused to imediately delete those indexes saved your job.
