To effectively run the read option it has to almost come natural to the QB. Golson just doesn't look natural at it and thus makes the wrong reads. It isn't as easy as it seems to properly run the read option, but it isn't rocket science either. If EG doesn't like contact, he is probably thinking more than just reading.
I watched Tim Tebow - who was dynamic at the read option at Fla - basically pick Nick Marshall apart on his read option decision making before the year started. And if you watch enough of Auburn, their offense goes as Nick makes his reads. Proper reads by him, and their offense turns completely into something different.
In the end, if the read option isn't something EG can effectively pull off, then it severly limits the Irish offense. I have seen too many bad reads that if EG would have read properly, he would have cake walked for 10-12 yards. Throw in moving the over the top safety in to provide run support, and the Irish passing game would then become dynamic.
