Running Backs in Pass Protection

Looking for some ideas of back responsibility in pass protection. We run a basic west coast offense and when we pass we rely mostly on quicks (3 step passes). However, when we do decide to run deeps ( 5 or 7 step passes), we get a ton of pressure. We would like to get the backs more involved.

Here is a system we are working on, I would like some feedback as well as suggestions.

--Two back set in the I with Quick Pass or Deep Pass called - A RED CALL - FB always goes to the right edge; HB always to the left edge and attacking the outside number of wide man; unless someone comes off the edge in which case the backs attack inside number of defender and runs him up the field and out of the play
--Two back set in I with a Quick Pass and one back running pass route or single back set - YELLOW CALL - back staying in goes to the TE side, again attacking outside number of widest defender; unless someone comes off the edge in which case the back attacks inside number of defender and runs him up the field and out of the play
--Two back set in the I with one back running pass pattern or single back set with Deep Pass called - ORANGE CALL - back blocks opposite the line call (if line call right, back blocks left edge attacking outside number of widest defender; unless someone comes off the edge in which case the back attacks inside number of defender and runs him up the field and out of the play

Any help or feedback would be greatly appcreciated.

Thanks
