Very smart by Bres imo. You want to see what players can just go out and make plays and beat the guy lined up across from them. Make their own reads, get off blocks, make tackles, practice shifting the defense as the offense shifts, etc. And if the offense capitalizes on the first two turnovers the defense got, then you can keep playing that way all game. When the offense violation the bed, thats when we had to adjust the defense and actually gameplan for a quarter or two. And we shut them down when we did that. I wouldn't say it was playing with fire, because as soon as we needed them too we turned up the heat and could have kept it on like that all game if it was closer. The reason Bres was so pissed about the scores(especially the late ones) is because even without mismatches giving us an advantage he still wants our guys to make the stops.
Basically Bres took himself out of the game and wanted to see what his players can do. Instead of us taking away what WCU can do best(the wr screen), we lined up and said okay lets see if we can beat them at their best with one hand tied behind out back. I promise you he still did his homework on WCU and we knew their play calls, etc. Its called a warm up, he let his guys get punched in the mouth a little bit and see how they respond. It wasn't pretty but it wasn't as bad as you all think it was either. The negatives I still saw were our DB's don't know how to get off a cut block to save their life and we were a little slow reading and reacting. There is no way to break up those screens with the scheme we were playing, but more of them should have been for little to no yardage.
But now this next game we can go out and exert our defense on Maryland and they won't know what is coming either. Do I expect us to do a complete 180 and not give up a single point to a much better school? No. But I think you will be much happier with the defensive scheme and see how we are actually doing different things to disrupt their offense.
