If you would have read my post carefully, you would have noticed I said this offense can work, because it has worked. That does not mean it will/will not work in the future, I am simply saying that it has the potential to work.
Yes, Oklahoma St's defense isn't really that good, but what does that matter when the pocket is collapsing? Taylor's ability to step up in the pocket and deliver an accurate pass downfield has NOTHING to do with the skillset of the players. Sometimes Taylor is indecisive, sometimes he isn't, and those things occur against both good and bad defenses. Why? I don't know, that falls on Watson. But, as my original post stated, we CAN be successful. Taylor CAN make the right decisions, CAN make the throws, and CAN kill other teams with his legs.
The scheme isn't the problem, it's executing that scheme weekly. I would think that it's pretty hard to argue that. Look at Washington as the best example. One time it worked, one time it failed. That's our problem, and that's why Shawn Watson needs to go. Not because he doesn't know offense or his X's and O's, but because it only works about 1/3 of the time for a reason nobody seems to be able to figure out.
