This is exactly what i was telling a friend of mine. EA/Tiburon has always made certain positions feel like dominating players based on ratings. Elite WR's and RB's have always been a problem to contain in the previous years.
I would love to see that translate to EVERY position, even Ofeensive linemen. If you have an elite, All-pro gaurd, you should be able to pound the ball behind him for gains UNLESS the defense over compensates to his side which in turn opens up other things for the offense. Walter Jones comes to mind in Seattle. They could TELL you they were running the ball and still get yardage. Dominating OL'men should get respect too.
Same thing as LBZ says here, if an ELITE pass rusher ala Freeney, Peppers, Umenyiora etc lines up against average or below average tackles, they should BLOW right by those medicre players at least a few times a game.
Also, the most glaring position is the QB position. There just isn't nearlt as much a difference between Manning and Tavaris jackson. IMHO, you should feel a HUGE difference in these players. There is NOTHING stopping you from lining up in shotgun with multiple wideouts with the Vikings. If the game was correct, you should NOT be able to do this. Playing with the Vikings should be just like the NFL. Give the ball to AP, play solid defense, and hope Jackson doesnt throw any INT's. Jackson should NOT be able to "WIN" them a game.
Ratings must apply to more positions throughout the game PERIOD. Having to overcompensate for a monster Offensive gaurd, having to throw away from an Elite CB Cover guy, having to send FB's or TE's to help block elite pass rushers is ALL what makes the NFL the "chess match" we all know it is. They are the "games within the game". This is what Madden has been missing.
