Here are my impressions:
We have had really good skilled athletes (qb, rb, wr) in the past, but have we ever had so many of them at the same time?
As has been noted, the defense is provoking turnovers and hitting harder than at any time in Wolford's tenure. They are not capable of playing at the old, traditional level that veteran fans expect, but if they can force two turnovers for every three touchdowns that they yield we will be ok.
For the third consecutive conference game, the defense shut out the opponent in the second half until garbage time (which arrived very early last night.) Even better, they seemed to make the adjustments on the fly after Illinois State's very easy first drive. Except for the long td pass (inexcusable of course) there was little to complain about.
Power, to respond to your point about the lack of a pass rush, is it not common to have defensive linemen that are run stuffers but inadequate pass rushers? We would like our guys to do both well, but stopping the run is imperative.
