I'd say some people would give it a chance if they knew it existed.
Oh, and one thing about the passing game is there aren't too many short pass plays. Like normally when you get a pass off in this game, you're looking at at least nine yards gained.
That's where there comes this issue with if you mess with the running speed of the players (their 40's are terrible) as well as the run blocking and such, there will be too much offense. Well I'd agree, but as a balancing point you could surely recreate some plays so that there are more short passes that are easier to make and long passes are more difficult.
Also, backing the QB camera up a couple of more clicks would be nice. I wish there was some other form of periphery as well, because I know that if I'm a QB and I'm facing east, even if I'm eyeballing a receiver that's north of me, I can still easily see what's coming east of me. Sometimes I can still see a bit of what's west of me, but this game doesn't really have any sort of way to tell you this. Even threat meters like in ESPN NFL 2K5's FPF feature would be nice, anything that can help you scramble and evade if you need to.
Oh, and scrambling in this game sucks. Just don't do it lol.
