John Reed's Clock Managment book

I OWN it, and have read it.
His book is very much "scientific", and kinda takes the feel away from the decisions that should be made on game day.
for example, unless I'm mistaken-and i haven't looked at it in a few years- he explains that the team that scores first is such and such percentage in an advantage, and should immediately go into a slow down mode with absolute maximum time used before each snap, conversely if you are down, even in the first quarter, you must go to your hurry up offense.
It is full of stuff like that and he does a very good job of making you think and using stats to back him up.
