So.... I thought they did about as well as anybody with stopping the run. I'm not going to pretend like they "solved" the problem, just like the Raiders didn't, but they had a pretty strong gameplan for stopping the run, and they executed it pretty well.
That being said... they also led pass catchers roam freely all day long, and give up chunk play after chunk play consistently in the passing game, which is almost certainly at least significantly contributable to an emphasis on stopping the run.
So while I agree with rossi that any decent coach can see this on film anyway, theoretically, if you found a team that could play the same style of run defense AND have sufficient talent in the secondary to play much better coverage than they did, then yes, you could, theoretically, have something.
That's also a gigantic task to ask of any defense in the league, and I don't really see any that have the talent to do both.
