I know NFL teams don't do too much trading, but the trading block doesn't quite show how much they do. Can't teams offer you trades?
And I don't think it should show who's benefitting from the trade with the colored bars. If the trade is being offered, it's probably for a reason, like deepening the depth chart, or coming up with a real starter.

Also, the player rating systems are a bit vague... and I don't think they really show the value each player can bring. Granted players like Peyton Manning are going to be rated 99, but as good as Ed Reed is, I don't think he should be a 99, or Ray Lewis for that matter either.
A player like Brandon Stokely, not a bad reciever, but it could easily be argued his numbers are purely the doing of Manning, shouldn't be rated as high as a player like Santana Moss, Aquan Boldin or Larry Fitzgerald, which he is very close to.
I think it's too easy for players to be considered elite players in the game. I mean, do a fantasy draft, and it's very easy to have a superstar player at just about every position.

I think tackling needs a little work, sometimes the CPU just bounces off the truckstick without making a move or slowing down.
WR catching could be improved by boxing out, or actually being able to catch one handed or by diving for the ball.

And if you're going to keep the Superstar Mode, don't let the superstar, a 3rd round draft pick no less, have control over the entire team.

And in Dyansty, when drafting players, they never come out all too talented. Why can't you draft a player like Braylon Edwards, Carnell Williams, Ronnie Brown etc. who can bring immediate talent to your team. Even with the first overall draft pick, I end up picking a 2nd or 3rd player, with little room for improvement.

Love the game, but still looking for improvement.
