It is bad and you really have to jack up their abilities and crush your defensive ones to get a tolerable run game. Like the poster above you said- the lack of deep balls adds alot too it. When you can take out the run and the deep ball. Is it really any surprise that we can pick off the CPU so often even if we raise run ratios and play at a proper difficulty (which alot don't)?
being what i feel is a realistic. I don't expect a new engine or anything insanely different for 2010 but i do expect deep balls and better running execution. When you need to defend multiple layers you not only get more variety which makes the game more fun but you get more difficulty.
So EA, Adam or anyone- at minimum- add deep ball, increase the running blocking and take the handcuffs off the LB, DB and QBs speeds. If you can add a real pocket- that would be great too.
