A lot of modes, a lot of plays, a lot improvements all around = A lot of fun
There are also a lot of game modes. My favorites are the on-and-offline dynasty modes. The presentation of stats, polls, and news is really top-notch, the recruiting is mildly addictive, and there are tons of awards that EA keeps track of to make it even more rewarding. I have only played Road to Glory a little, but it seems cool. My player was a FS who the AI chose to avoid...so I haven't seen much action yet, and I am getting used to the new camera angle. Teambuilder also is cool feature that stayed on from last year's release. So, there is a lot of stuff here to do besides play a great game of ball.
My top two complaints would have to be that defensive lineman catch a speed demon like Denard Robinson from behind way too often (like always when scrambling from the pocket). And change of direction leaves a little to be desired, as I see players on TV cut way harder and a lot more explosively.
But in context to the game as a whole these are nothing. With the plethora of playbooks and modes, great graphics, realistic enough gameplay, and (at least I think) challenging AI, this is a solid football game. But cut blocking has to be worked in if EA is going to make the option an option.
