Let's go ahead and try and read a bunch into fall practices, because that always works out well!
It's always dangerous to try and read too much into practice performances when it comes to predicting future success. Is defensive success good because the defense is actually good, or is it bad because the offense is actually bad? You obviously can drive yourself nuts.
That said ... I'm going to jump on the Gravitron and do it anyway!
One consistent theme throughout practice reports has been the ability of the defense to generate pressure on the quarterback.
