Anyone that doesn't see the OL problems is not paying attention. Go back and watch the last play before the failed FG attempt against CU. Blocking is one thing and that has not been stellar for certain but who to block and when is another piece. They can't get the communication right and when they do, someone manages to whiff way too often. They may make initial contact only to slide off and let their guy make the play, no drive. A lot of diving for cut blocks only to have the D step over them. Even their position coach commented they can't even get out of their stance. With all of the complaining that took place under Riley about OL play, people need to hold their water just a bit here because it is not where it needs to be.
The spread O, in general, stretches the D sideline to sideline and vertically, that creates the holes and spaces. Where is the deep threat to stretch the D? Noa hasn't caught a single ball. You could see the CU D come closer to the LOS as the game went on and keep everything in front of them to negate the supposed speed advantage we had. Washington broke one down the left side, but other than that, our side to sideline and vertical stretched game is not working right now. All the speed we hear about hasn't showed up very often - yet. We can't even get a WR open although everyone will point out the time they "saw someone open" when Adrian is scrambling and rolling to his right. There are often guys open, some of that is a clear out and there is no way to get the ball to them. some are calling for Adrian to roll out more, fine, you just shrunk the amount of field to cover and it keeps your speed receivers in a smaller area. There is a place to use it but not all of the time.
I expect NIU to come out and move their D all over the place making communication difficult for out OL and the will likely keep their LB's close to the LOS to close the speed gap. Guess right and get a crease and there can be some long plays but some frustration along the way. Just my opinion.
