You hate all read option or just his version of it?
I hate all option, except RPO stuff. That means either hand off to the RB or throw to WR on the slant or whatever depending on what the LB or safety does. Pro RPO, not pass/keep stuff.
RPO pass/keeper stuff, as you mention, I hate most of that.
As I said, option is high risk, low reward. Too many unblocked DEs/EMOL and too many hits behind scrimmage. Too many turnovers (for the risk). Too many mishandled balls when the QB tries to pull it back. Too little yardage. Too many 3rd and 8s.
Take some time and watch replays of our backs getting hit in the backfield and watch the backside DE. When he is unblocked, that is a read option. There's more to it, but once you see that you will probably recognize the rest. So many times people have been bytching at the DEs when those guys are just running the play that was called.
As for passing, sideways is ok, but it takes no longer time to run just two strides behind the LBs. I don't know why Mullinz is so infatuated with short passes. The WRs often juke once or twice anyway then turn for the ball, so it is still basically a three step drop coming in about three seconds. They too are much more dangerous. A pick is often a pick 6 with those. In the same time we could be running a medium route (around 11 yards, LBs usually drop to 7 yards) and still be getting a very high percentage pass.
SOS made his money on medium passes, 11-17 yards deep. People forget that. It's how you end up with Wuerffel and the others close to 70%.
