Gotta play a few games to really get everything down defensively, at least I had to. It also would depend on the ratings of the offensive line you were against, even an average line could make a scrub look halfway serviceable, we've seen it happen multiple times on TV. And remember, it's All-Madden, not only is it supposed to be hard but sometimes cheesy things will happen, kinda gotta roll with the punches there. If it keeps happening at an entirely unrealistic pace, like if the Seahawks or 9ers gash you hardcore, maybe adjust something a little. Hopefully this was helpful in any way, my man.
