I absolutely agree. They really don't give you the manuverability in the pocket like your running qb's of today have. On top of that, when I play the computer and I am playing the Saints, I don't want to see them run the ball with Pierre Thomas all game. For starters, we all know they LOVE throwing the ball, and for two, they have 8 different running backs that they use.
Also to add on to this, despite Wes Welker having a great overall rating, he will never be lined up at the Z receiver and be used the same way Calvin Johnson is. Allow for the game to have roles for player like there is in real life. even though Wes Welker and Brandon Marshall may have the same rating, they play two different styles of football.
