Great game for true football fans who know their game and want to play something more than a button mashing simulation.
There is plenty to do, and you have to keep tabs on your players, salary cap, GM and owner expectations, and team philosophy. Timing is critical too. You don't have all day to do research (but you still better research your prospects). Setting priorities helps, but ultimately, to get the full experience, click the "A" button as much as you can.
I don't like that the game doesn't have post game press conferences or half time coaching adjustments, but maybe these (great) ideas will be in next year's game. I just hope there is a next year's game. While the game has received good reviews, sales may be lacking and cause EA to suspend a 2010 release.
Bottom line: Buy this game, either by itself or with the Madden 20th Anniversary Edition and enjoy all that being a head coach has to offer (at least most of it). I do have my gripes, but I think it's a solid, well thought out and built game for true football fans.
