I for one, think we probably involve Waters in the running game quite a bit, but far different from anything we've seen since at least 2010. I think it's extremely unlikely that we do the QB/RB option read out of the shotgun, or the QB designed runs between the tackles like we saw out of Klein, and then Sams/Waters last year.
RATHER, I think we see a return of the bubble option that CCQ made so famous. Hey, that was marginally effective, and CCQ was in charge. I don't think it's a stretch (lil running game humor
) to say that Waters is probably a better runner that Coffman was. That could be a really solid set, especially if we line up Lockett in the slot.
Additionally, I think we do some more conventional option plays with Gronk lead blocking. Hate on Waters all you want, but when we ran the conventional option last year, he was pretty damn good at (1) deciding when to pitch and (2) accurately pitching it.
These are only a few great ideas on how to effectively run the ball without experienced running backs!
