Defemse still gives up long yardage - can't come through when needed.
Defense can't come through when needed? And how many field goals did Purdue have to settle for after we handed them the ball in front of our goal line?
This defense is by no means a bunch of world-beaters, but lay the fuck off. Most of the points scored on them this year have been on drives where the opposing offense was handed the ball in our territory. When your offense and special teams repeatedly paints your D into a corner, and tops it off by going 3-and-out all the time, you're going to give up points no matter how good your D is.
If our D is so horrible Purdue would be at about 40 points right now at halftime. If our offense didn't keep telling our D to "roll over and take it like a man" then this game would be a helluva lot closer.
The defense is by no means perfect and has given up some big plays, but it's the ineptitude and mistakes on offense that are putting the final nails in the coffin.
