The only way you can spy a QB like Robinson/White is if you have an athlete in the front 7 who is good enough to tackle Robinson/White in space, at least on occasion. Most teams don't have that.
Aside from that, the best thing you can do is keep outside containment and gang tackle. If I were a DC trying to stop Robinson right now, I'd have my DE stay home on the zone read option and make Vincent Smith/Mike Shaw/whoever beat me from the running back position. Hopefully the front-side defenders can make the tackle and hold them to minimal gains.
That scrape exchange stuff works fine for quarterbacks who aren't that mobile (Forcier, for example) because the DE can make a play on the more dangerous RB, and the OLB coming over the top can often keep up with a guy like Forcier. But even most OLBs are going to be made to look silly by a guy of Robinson's athleticism.
