Firstly, unless you are very familiar with the intricacies of American Football you are likely to get lost in this game instantly. It is NOT a pick up and play game. You need reasonable knowledge of how a NFL franchise actually works. If not, then you need to read up quite extensively.
However, if you are willing to put the time and effort into the game then it is a rewarding, albeit slow, experience. I have not experienced many of the problems a previous reviewer pointed out and to be honest if you don't want to do the draft then why are you buying a NFL Head Coach game, the draft is a key element of the game. It is like playing Football Manager without wanting to get involved in signing players!
The match experience usually takes around 45 minutes a game and runs similar to a Madden game. Presentation is ok, but not a televeised experience like Madden. It is more like what a head coach would see. It definitely needs tidying up a bit and it doesn't give you vital information like if an opposing side has a key player injured during the game.
I may be wrong, but I also felt as though games were kind of manipulated to usually finish in a close match. For instance, you could be 17 points up and in posssession with 5 mins to go. Then you fumble the ball, they score then kick off to you and you fumble and lose possession and just about hang on. That kind of thing. Maybe it was just my imagination though.
All in all I found it a really good game with a few drawbacks. I would love to see a new version come out but in the meantime this is definitely worth a shot.
