That's what sliders are for. With proper sliders the read option is perfectly fine. I run a run-first spread option attack and I've had some really good option QBs. So far (through 2024) I've only had 1 QB rush for 1,000 yards in a season and I've never had one average 5 YPC (the OP's ridiculous numbers has his QB averaging 8.5).
Here are all of my 900+ yard rushers so far. Even my HBs #s aren't crazy as I haven't had anyone average 6 YPC. My rushing #s are actually too low compared to real life, but I prefer that to over inflated numbers like the OPs.
