There was one play that Helu was in the backfield and he went to chip up the middle... where there was no rush. Aldon smith got around Moses and blew up Griff from behind. Is that an instance where Griffin needs to change the protection at the line when he saw where the pressure could be coming from? I couldn't tell if Helu was on a delayed leak out to the flat, or if he was there for help in blocking and when nobody came up the middle he tried to make himself available as a check down.
I think thats the last sack your talking about. Its hard to be definitive about these plays without knowing exactly what the play call was or the blocking rules are for the called protection. However normally I would expect a back to have a check release in that situation i.e. he checks whether a key defender he is matched with rushes, if that defender rushes he blocks him if he drops into coverage the back releases into a pattern. Normally you have big on big - so your o'Line block their D'Line and in a 3-4 the two OLBs as well. Helu probably had a check on one of the safeties or the inside 'backer.
Now this is where game planning comes in. Its not rocket science to think that Moses might have some issues in obvious passing situations with Aldon Smith. So what I would have done at a minimum is have Helu release outside and chip Smith on his way into a pattern in the flat rather than releasing up the middle even if the guy he was reading was in the middle of the field. I'd also have lined Paul up outside Moses and had him chip Smith as well as he released. That might compromise what patterns you can run with Helu and Paul but thats not as much of a compromise as having your QB sacked within 2 seconds of the snap. I don't think thats a protection Griffin can change, its part of the play call, I also don't think Griffin calls the protections, we have Lich do that from centre.
