It happens, Clemson had their number for a number of reasons. #1 Deshaun Watson is a beast and is by far the best QB in the country. Second Foster struggled bad trying to "spy" him, Rashaan Evans played a hell of a lot better in that role. A lot of the game seemed like they were more worried about letting big plays get behind the defense and it worked in the sense of Clemson wasn't able to hit the big bombs down the field, but the 20+ yard plays killed the defense. They had us on our heels most of the night and it seemed like we weren't aggressive in the pass rush, likely trying to keep from getting hurt worse with Watson scrambles, but that hampered the defense even more as it put even more pressure on the secondary and linebackers to not only drop back in coverage but when Watson scrambles go corral him. Even with the yardage and the score they still forced Clemson to punt seven times and Eddie had the HUGE turnover.
So you can call it being "exposed" and try to diminish what the defense accomplished during the season and how good the defense truly is/was, but it is just another bullshit knee jerk reaction we see the media throw out there constantly. There were many times this year that the defense bailed the offense out and against Clemson the offense, defense, and special teams all had to come up big at different times to win. Thats why it is called a TEAM game tho... one of the many reasons Im proud as hell of this team.
