OL is definitely a huge issue and is the core of a lot of our problems. Dak usually has no time to throw. Guyton is terrible but mainly due to him playing Tackle when he only played Guard at OU. Whose bright idea was it to do this? Zack Martin is at the end of his career. Tyler Smith still has room to grow for sure. Just isn't a great unit. Reminds me of the OL's we had before Tyron/Martin/Frederick were in place as a trio. Not good.
Adding another WR here would do zero because we don't even have adequate time to throw the ball.
