ESPN has a pretty in-depth profile of the people in the Cowboys war-room on draft day and the role they play in the decision-making. The main ones you know very well - but a few I hadn't heard much about. Most important 3 days of the year for many of them.
I particularly recommend the profiles and little anecdotes on the in-animate objects in the room:
- the board (and how coaches would sneak in an move their favourite players up the rankings)
- the computer ("I bow to the machine")
- the books (the Mel Renfro storry - imagine how long the draft would take without time limits....)
