I think that'll be the big x-factor. Julio's a huge part of what they do and that's obviously not going to change, but the running game going forward is the big question (and whether they can replicate it without Shanahan). Like you say, you can't double Julio because they'll run down your throat, you can't stack the box because Julio will put 200 yards on you - and that makes them (much) better than the sum of their parts. There were some pretty terrible teams with Julio alone.
