At least early on, Levis had time. Took a sack when CRod was all by himself in the flat. Levis has NOT improved his decision making, seeing the field, looking off defenders, etc. That's all on Scan as QB coach and OC.
The line has its issues. When you are extremely predictable on almost every series, you have no plan to stretch/exploit the defense, you have your presumed NFL QB throw sideways time after time, you almost never trick the defense, etc, I think your OC is not doing a very good job workinh around an OL that is sub par. Stoops doesn't call the plays. Maybe he influences the game plan but tonight's was doomed to fail.
I posted earlier this week that we have to exploit TN porous secondary by quick slants, seams off PA, throw on 1st down, etc. We did the exact opposite pretty much all night. Run 1st and second down then call 5- and 7-step drop pass plays that take forever to develop. TN blitzes a lot. We had to make them pay and never seemed to even try.
