I re-watched Sunday’s game between the Texans and Vikings. That screen play called on 4th and 16 that so many rightly criticized? It came after a big third down sack that occurred when Xavier Su'a-Filo missed his block by a mile. Su’a-Filo looks utterly confused on so many plays. Most often when protection breaks down, it's either Su’a-Filo, Chris Clark, or Jeff Allen who blew an assignment, wandering around aimlessly while Brock Osweiler or the running back gets pounded into dust. While Brock certainly had several “WTF?” moments, the offensive line needs to work better together as a unit.
